Subject: drm/vkms: Dont flush crc worker when we change crc status
Git-commit: 64cfaa5092715a00a5cdbd3d804d16a38554fe40
Patch-mainline: v5.4-rc1
References: bsc#1152472

The crc core code can cope with some late crc, the race is kinda
unavoidable. So no need to flush pending workers, they'll complete in
time.
