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
Signed-off-by: Jason Dillaman <dillaman@redhat.com>
(cherry picked from commit 6ec431bac1cf9446f3af90209d193dfcf003f2c5)
