cifs: Don't advance the I/O iterator before terminating subrequest

Browse source 
There's now no need to make sure subreq->io_iter is advanced to match
subreq->transferred before calling one of the netfs subrequest termination
functions as the check has been removed netfslib and the iterator is reset
prior to retrying a subreq.

Fixes: 3ee1a1fc39 ("cifs: Cut over to using netfslib")
