receive: account for napi_gro_receive never returning GRO_DROP
The napi_gro_receive function no longer returns GRO_DROP ever, making handling GRO_DROP dead code. This commit removes that dead code. Further, it's not even clear that device drivers have any business in taking action after passing off received packets; that's arguably out of their hands. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
