A status member of spdk_bdev_io structure is set after the if block.
Therefore a status parameter should be checked instead of a status
member.

The value of CAP should not change during the lifetime of a controller,
so read it once during ctrlr_construct and store it in the ctrlr.

Rather than embedding adminq directly in the spdk_nvme_ctrlr structure,
change it to a pointer to a spdk_nvme_qpair. This is necessary to allow
the transport to extend the qpair structure.

This requires a couple of related changes:
- I/O queue IDs are now allocated by using a bit array of free queue IDs
instead of keeping an array of pre-initialized qpair structures.
- The "create I/O qpair" function has been split into two: one to create
the queue pair at startup, and one to reinitialize an existing qpair
structure after a reset.

This is required since pollers are now directly removed
(rather than scheduling an event) when the unregister call
is made on the poller's lcore.
Without this change, if a poller is registered then
immediately unregistered, the unregistration will seg
fault since the event adding the poller has not executed
yet.
Also add a test case that exhibits the sequence of events
described in this commit message.
