avdevice/v4l2: Remove av_assert0 when format not supported
Before this commit an av_assert0 would fail if a v4l2 device did not
support a target format.
For example,
./ffmpeg -f v4l2 -codec:v h264 -i /dev/video0 -f mpegts -
would signal an abort if /dev/video0 did not support h264.
The new behaviour is to return an AVERROR(EINVAL) error code. An
av_assert0 has been added to verify this return.
Fixes #6629
