[PATCH 5.15.y 1/2] backlight: lm3630a_bl: Remove redundant 'flush_workqueue()' calls

[Sasha Levin <sashal@kernel.org>]

From: Xu Wang <vulab@iscas.ac.cn>

[ Upstream commit adc122011125682932ef279d717153670feedde4 ]

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

Remove the redundant 'flush_workqueue()' calls.
