CIFS: Fix trace command logging for SMB2 reads and writes

CIFS: Fix trace command logging for SMB2 reads and writes

commit 7d42e72fe8ee5ab70b1af843dd7d8615e6fb0abe upstream.

Currently we log success once we send an async IO request to
the server. Instead we need to analyse a response and then log
success or failure for a particular command. Also fix argument
list for read logging.
