f_auto_filters: always fall back to hw-download+yadif if no hw deint filter 

If hw decoding is used, but no hw deinterlacer is available, even though
we expect that it is present, fall back to using hw-download and yadif
anyway. Until now, it was over if the hw filter was somehow missing; for
example, yadif_cuda apparently requires a full Cuda SDK, so it can be
missing, even if nvdec is available. (Whether this particular case works
was not tested with this commit.)

Fixes: #7465
