libertas: fix sanity check on sequence number in command response
David Woodhouse [Mon, 3 Mar 2008 11:20:12 +0000 (12:20 +0100)]
Slightly more useful if we compare it against the sequence number of the
command we have outstanding, rather than comparing the reply with itself.

Doh. Pointed out by Sebastian Siewior
