In the compose menu, mutt_view_attachment() calls
mutt_decode_save_attachment(), which calls mutt_parse_parts().
This function took care to save the m->hdr and m->parts but only
restored for the case that m->parts previously existed. As noted in
the previous commit, mutt_message_to_7bit() removes parts and keeps
hdr. So the restore was not taking place, leading to a memory leak in
this case.
Change the restore to check for either parts or hdr.
