Use a direct firmware command to destroy the mkey in case the unreg UMR
operation has failed.
This prevents a case that a mkey will leak out from the cache post a
failure to be destroyed by a UMR WR.
In case the MR cache limit didn't reach a call to add another entry to the
cache instead of the destroyed one is issued.
In addition, replaced a warn message to WARN_ON() as this flow is fatal
and can't happen unless some bug around.
