5.15-stable review patch.  If anyone has any objections, please let me know.

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit e8d585b2f68c0b10c966ee55146de043429085a3 ]

'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);
	destroy_workqueue(E);
