avcodec/exif: avoid leaking EXIF metadata upon parse failure
Before this commit, exif_parse_ifd_list didn't free *ifd upon failure,
relying on the caller to do so instead. We only guarded some of the
calls against this function, not all of them, so sometimes it leaked.

This commit fixes this, so exif_parse_ifd_list freeds *ifd upon failure
so callers do not have to guard its invocation with a free wrapper.

Fixes: ossfuzz 440747118: Integer-overflow in av_strerror
