Reviewed-by: Loic Dachary <ldachary@redhat.com>
librbd: prevent race condition between resize requests
It was possible that the same resize request could be sent twice
if a completed resize op started a newly created resize op while
it was also being concurrently started by another thread.

Fixes: #12664
Backport: hammer
