Module initializaiton was made asynchronous recently
to support bdev modules like gpt which need to do
asynchronous I/O. But all modules now do any
asynchronous I/O in their examine() routines, and
init functions only do very basic operations to be
ready to handle examine() callbacks.
So simplify the bdev code and modules to go back to
a synchronous init procedure.

vbdev modules still open/close bdevs as normal, but
should open bdevs read only when tasting (i.e. reading
the GPT to see if there are SPDK partitions). When
a vbdev module is ready to claim the bdev for purposes
of creating virtual bdevs on top of it, it calls
spdk_vbdev_module_claim_bdev(). It can pass its
open descriptor as well to have it promoted to
write access (required for future vbdev modules like
logical volumes).
Note: error vbdev was changed to copy the base bdev
parameters one-by-one instead of a blind memcpy - we
do not want to copy the base bdev's vbdev_claim_module
into the new bdev!

Previously, we had a pdu->ahs pointer that was always NULL (never set

initiator ever sent a PDU with a non-zero TotalAHSLength.
Rename the existing ahs_data array in the PDU to just "ahs" to minimize
the necessary changes. We never actually dereference the ahs structure,
so its type is not important. (We can cast it later if we add support
for anything that requires an AHS.)

During RocksDB testing with MySQL, we found cases
where blobfs would try to update and sync the length
xattr on the underlying blob while an existing update
was already in progress. This was primarily driven
by RocksDB performing appends and syncs on the log
file from multiple writer threads.
The simplest way to fix this is to just process one
sync_request at a time. There could be a tiny bit
of inefficiency here if multiple threads are appending
and syncing a file in parallel - we can look at some
additional optimizations if we find a case where that
is noticeable.

This requires the following modifications to existing
bdev modules:

at examine time (instead of init) to see if the
bdev should be consumed by the vbdev module
2) gpt is simplified considerably - it no longer
needs to save bdevs to examine when
gpt initializes later
3) nvme must register its io device before registering
the bdev, since vbdevs may immediately start trying
to send I/O to the new nvme bdev
