iwlegacy version of fix:

commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc

iwlagn: fix command queue timeout

If the command queue is constantly busy,
which can happen in P2P, the hangcheck
timer will frequently find a command in
it and will eventually reset the device
because nothing sets the timestamp for
this queue when commands are processed.

Fix this by setting the timestamp when
a command completes.

iwlegacy does not support P2P, but this patch fix possible
unneeded hardware resets, hence is needed.
