Pacify warnings from gcc 12 in encode_coding_object

* src/coding.c (encode_coding_object): Mark saved_pt_byte with UNINIT
to silence a false alarm from -Wmaybe-uninitialized.  This was already
done in decode_coding_object.  The fix is correct because saved_pt is
used as a sentinel before saved_pt_byte is used (bug#57219).
