Resolve function name conflict (media/filters)

When building using jumbo, files merged and functions with
the same name may end up in the same namespace/scope. This
happens for the function OnError() that gets called by Bind().
OnError() is defined in:
media/filters/audio_video_metadata_extractor.cc
media/filters/media_file_checker.cc

This commit solves the issue by renaming one of the functions
to something more file specific.
