V4L/DVB (9911): em28xx: vidioc_try_fmt_vid_cap() doesn't need any lock

Browse source

vidioc_try_fmt_vid_cap() just checks if a given resolution is supported.
It doesn't touch on struct em28xx device descriptor. so, there's no need
to lock.

While there, use unlikely() for those values that aren't likely to
occur.
