[PATCH] media: v4l2-mem2mem: Fix spurious v4l2_m2m_buf_done

From: Ezequiel Garcia
Date: Mon Sep 28 2020 - 10:04:11 EST


A seemingly bad rebase introduced a spurious v4l2_m2m_buf_done,
which releases a buffer twice and therefore triggers a
noisy warning on each job:

WARNING: CPU: 0 PID: 0 at drivers/media/common/videobuf2/videobuf2-core.c:986 vb2_buffer_done+0x208/0x2a0

Fix it by removing the spurious v4l2_m2m_buf_done.
