vf_format: simplify frame type checking after addition of DoVi option 

We only wish to touch actual video frames, which should have an
allocated image attached to them, so just check the frame type
early, and exit by passing through such non-video frames to further
filters in the chain without attempting to process them.

Fixes a crash in case of non-video (EOF/NONE) frames being passed
onto the filter when the dovi option was set to false since
05ccc51d53 .
