ass_mp: reset packer when allocation fails 

Sometimes the atlas can get so large that it exceeds the maximum allowed
size for an mp_image. Since the atlas will never shrink naturally, this
breaks subtitles entirely until mpv is restarted. Reset the packer so
that subtitles can rendered properly once the atlas fits again.

This is a partial workaround for #6286.
