Subject: [PATCH] media: mtk-jpeg: Fixes jpeg enc&dec worker sw flow
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 86379bd9d399e2c5fd638a869af223d4910725c3

[ Upstream commit 86379bd9d399e2c5fd638a869af223d4910725c3 ]

1. Move removing buffer after sw setting and before hw setting
in enc&dec worker to prevents the operation of removing
the buffer twice if the sw setting fails.
2. Remove the redundant operation of queue work in the
jpegenc irq handler because the jpegenc worker has called
v4l2_m2m_job_finish to do it.

Fixes: 5fb1c2361e56 ("mtk-jpegenc: add jpeg encode worker interface")
Fixes: dedc21500334 ("media: mtk-jpegdec: add jpeg decode worker interface")
