This patch adds support for using zero-copy operations to execute IO
requests in the TCP transport. Of course, they're only used if the
underlying bdev supports them. Additionally, only requests with no
in-capsule-data can be executed using this mechanism.
Added several new states to accommodate for the difference in a way
zero-copy is handled. Also, these flows very depending on the type of a
request (read or write). It stems from zero-copy semantics: to perform
a write we need to wait for zcopy_end completion, while for reads
zcopy_end can only be submitted once we send all of the requested data
to the host.

Zero-copy requests are kept on the outstanding queue for the whole
duration of the request - from the initial zcopy_start submission to the
completion of zcopy_end. This means, that there's a period in which a
request doesn't wait for a completion from the bdev layer, but is still
on the oustanding queue (after zcopy_start callback, before zcopy_end
submit). If a qpair gets disconnected while a request is in this state,
we need to manually force its completion, as otherwise it might hang
indefinitely (e.g. waiting for host data).

The zero-copy requests can also be queued when a subsystem is paused, so
we need to properly resume and submit them by using zcopy_start.
Since only requests that haven't received the zero-copy buffer (i.e.
before zcopy_start was called) can be queued, we don't need to bother
with checking zcopy_phase.

We have very frequent failures when we run test/nvmf/host/multipath.sh

Call stack showed nvmf_stop_listen_disconnect_qpairs() accessed
qpair->ctrlr even if qpair->ctrlr was NULL.
nvmf_stop_listen_disconnect_qpairs() did not check if qpair->ctrlr is
not NULL before accessing qpair->ctrlr->subsys.
When a qpair is added to a poll group, qpair->ctrlr is cleared to NULL.
The test code test/nvmf/host/multipath.sh executes multiple
reconnects for path error.
So a conflict might occur between adding a qpair to a poll group and
disconnecting a qpair in a poll group.
In this case, it may be acceptable even if we disconnect a qpair whose
qpair->ctrlr is NULL. It will be better than SIGSEGV.

will still get updated when those listeners are removed.

When NVMe passthru command (IO or admin) fails on submission (e.g. it
is not supported), set DNR bit in completion status field. There is no
sense in retrying the command in this case.

Calculate supported maximum number of queue pairs based on
BAR0 size, this value isn't allowed to change at runtime, also
define BAR4/5 based on number of MSIX vectors.
Since the maximum number of queues is a large value(512), so we
still define a default value when starting, users still can
overwrite this value with a number no greater than 512.
