[media] v4l: vb2: Fix race condition in _vb2_fop_release
The function releases the queue if the file being released is the queue owner. The check reads the queue->owner field without taking the queue lock, creating a race condition with functions that set the queue owner, such as vb2_ioctl_reqbufs() for instance. Fix this by moving the queue->owner check within the mutex protected section.
