Subject: [PATCH 5.4 039/110] net: socionext: fix xdp_result initialization in netsec_process_rx

From: Lorenzo Bianconi <lorenzo@...nel.org>

[ Upstream commit 02758cb6dac31a2b4bd9e535cffbe718acd46404 ]

Fix xdp_result initialization in netsec_process_rx in order to not
increase rx counters if there is no bpf program attached to the xdp hook
and napi_gro_receive returns GRO_DROP

Fixes: ba2b232108d3c ("net: netsec: add XDP support")
