Jim Harris c12d468d02 nvmf: retry QID check if duplicate detected 
A host will consider a QID as reusable once it disconnects
from the target.  But our target does not immediately
free the QID's bit from the ctrlr->qpair_mask - it waits
until after a message is sent to the ctrlr's thread.

So this opens up a small window where the host makes
a valid connection with a recently free QID, but the
target rejects it.

When this happens, we will now start a 100us poller, and
recheck again.  This will give those messages time to
execute in this case, and avoid unnecessarily rejecting
the CONNECT command.

Tested with local patch that injects 10us delay before
clearing bit in qpair_mask, along with fused_ordering
test that allocates and frees qpair in quick succession.
Also tested with unit tests added in this patch.

Fixes issue #2955.
