.ctrlr_connect_qpair
Previously this was assumed to be a synchronous process so the generic
layer transport code updated the state after .ctrlr_connect_qpair
returned. In preparation for making this support asynchronous mode,
shift that responsibility down into the individual transports.
While none of the transports actually do this asynchronously, insert a
busy wait in nvme_transport_ctrlr_connect_qpair to wait for the qpair to
exit from the CONNECTING state. None of the upper layer code can
actually correct handle a transport doing this asynchronously, so the
busy wait will cover that.

fail with -EPERM, because the snapshots are marked as read-only.
Additionally, zero-length non-vector requests are now completed

cluster copy.

Split the NVMe controller reset into pre-init and reinit stages so
that the latter begins with a call to nvme_ctrlr_process_init(),
returning -EAGAIN if the controller is not yet ready so that a poller
can call it again later.

BUG FIX: call nbd_bdev_hot_remove will stuck if
it is called when nbd has in-flight IOs.
nbd_bdev_hot_remove is asynchronous. It will
guarantee the stop of this nbd.
nbd hot remove test will be added later

This parameter is still part of API spdk_sock_impl_opts
structure but it is not used. Keep it to support ABI
compatibility since it is located in the middle of the
structure and removing it may break socket opts initialization
or parsing.
