LU-11251 mdt: ASSERTION (req_transno < next_transno) failed

An update request is checked for duplicates by xid in
is_req_replayed_by_update(). However xid is unique per
client only. It may happen that there are 2 requests
with the same xid from different clients.

Perform lookup by transno, it is unique per MDT.
