[PATCH 5.7 174/265] socionext: account for napi_gro_receive never returning GRO_DROP

[Sasha Levin]

From: "Jason A. Donenfeld" <Jason@xxxxxxxxx>

[ Upstream commit e5e7d8052f6140985c03bd49ebaa0af9c2944bc6 ]

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.

Fixes: 6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in napi_gro_receive()")
