From: Aharon Landau <aharonl@xxxxxxxxxx>
The vendors set the IOVA of newly created MRs in rereg_user_mr, so don't
overwrite it. That ensures that this field is set only if IB_MR_REREG_TRANS
flag is provided.
Fixes: 6e0954b11c05 ("RDMA/uverbs: Allow drivers to create a new HW object during rereg_mr")
