[AD] very small fix for MIDI.c

[Javier González <xaviergonz@xxxxxxxxxx>]

hello
attached is a patch for midi.c
as you may now, midi files can be type 0 or type 1
and this line

data = pack_mgetw(fp);                    /* MIDI file type */
if ((data != 0) && (data != 1))
  goto err;
check that if
suppose data is 0.... it wont go err
suppose data is 1.... it wont go err
suppose data is 3... it wont go err!
that's why i've changed it to be if ((data != 0) || (data != 1))

patch attached

have fun ;)
