mac80211: don't use napi_gro_receive() outside NAPI context

Browse source

commit 22d3a3c829 upstream.

No matter how the driver manages its NAPI context, there's no way
sending frames to it from a timer can be correct, since it would
corrupt the internal GRO lists.

To avoid that, always use the non-NAPI path when releasing frames
from the timer.
