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

------------------

From: Hans Verkuil <hans.verkuil@cisco.com>

commit b2469c814fbc8f1f19676dd4912717b798df511e upstream.

Don't duplicate the buffer type checks in enum/g/s/try_fmt.
The check_fmt function does that already.

It is hard to keep the checks in sync for all these functions and
in fact the check for VBI was wrong in the _fmt functions as it
allowed SDR types as well. This caused a v4l2-compliance failure
for /dev/swradio0 using vivid.

This simplifies the code and keeps the check in one place and
fixes the SDR/VBI bug.
