mac80211: don't send null data packet when not associated
commit 20f544eea03db4b498942558b882d463ce575c3e upstream.
On resume or firmware recovery, mac80211 sends a null
data packet to see if the AP is still around and hasn't
disconnected us. However, it always does this even if
it wasn't even connected before, leading to a warning
in the new channel context code. Fix this by checking
that it's associated.
