RDMA/erdma: Extend access right field of FRMR and REG MR to support atomic

Browse source

To support atomic operations, IB_ACCESS_REMOTE_ATOMIC right should be
passed to hardware for permission check. Since "access mode" field in FRMR
SQE and RegMr command is never used by hw, we remove the "access mode"
field, so that we can then have enough space to extend access fields.
