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. Cc: #2.6.39, #3.0.0 #3.1.0 Signed-off-by: Johannes Berg <> SIgned-off-by: Wey-Yi Guy <> Signed-off-by: John W. Linville <>
