net: Fix napi_gro_frags vs netpoll path
[ Upstream commit ce9e76c8450fc248d3e1fc16ef05e6eb50c02fa5 ]
The netpoll_rx_on() check in __napi_gro_receive() skips part of the
"common" GRO_NORMAL path, especially "pull:" in dev_gro_receive(),
where at least eth header should be copied for entirely paged skbs.
