media: venus: vdec: fix format enumeration
find_format_by_index() stops enumerating formats as soon as the index
matches, and returns NULL if venus_helper_check_codec() finds out that
the format is not supported. This prevents formats to be properly
enumerated if a non-supported format is present, as the enumeration will
end with it.
Fix this by moving the call to venus_helper_check_codec() into the loop,
and keep enumerating when it fails.
Fixes: 29f0133ec6 media: venus: use helper function to check supported codecs
