mailinfo: move check for metainfo_charset to convert_to_utf8()
All callers of this function refrain from calling it when mi->metainfo_charset is NULL; move the check to the callee, as it already has a few conditions at its beginning to turn it into a no-op. Signed-off-by: Junio C Hamano <gitster@pobox.com>
