[media] drivers/media: vsp1_video: fix compile error

This was found with the -RT patch enabled, but the fix should apply to
non-RT also.

Compilation error without this fix:
../drivers/media/platform/vsp1/vsp1_video.c: In function
'vsp1_pipeline_stopped':
../drivers/media/platform/vsp1/vsp1_video.c:524:2: error: expected
expression before 'do'
  spin_unlock_irqrestore(&pipe->irqlock, flags);
