[PATCH 5.15.y 1/2] media: mtk-vpu: Remove redundant 'flush_workqueue()' calls

[Sasha Levin <sashal@kernel.org>]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 360c887a39cb56e75be4f558b16f1b6409ecb93f ]

'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.

Remove the redundant 'flush_workqueue()' calls.

This was generated with coccinelle:

- 	flush_workqueue(E);
