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

[ Upstream commit 22d3a3c829fa9ecdb493d1f1f2838d543f8d86a3 ]

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.
