media: v4l2-ioctl.c: use check_fmt for enum/g/s/try_fmt

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.
