RDMA/irdma: Enforce local fence for IB_WR_REG_MR

Browse Source 
Enforce local fence for IB_WR_REG_MR to avoid spurious
FASTREG_VALID_MKEY async events during heavy invalidation
and registration activity.

Commit 69e8e429bc ("RDMA/irdma: Enforce local fence for LOCAL_INV WRs")
was very similar, but was not sufficient to prevent all occurrences
of these async events.

Fixes: b48c24c2d7 ("RDMA/irdma: Implement device supported verb APIs")
