[PATCH -next v2] packet: remove unused variable 'status' in __packet_lookup_frame_in_block

From: Mao Wenan
Date: Mon Jun 10 2019 - 21:29:14 EST


The variable 'status' in __packet_lookup_frame_in_block() is never used since
introduction in commit f6fb8f100b80 ("af-packet: TPACKET_V3 flexible buffer
implementation."), we can remove it.
