pcm: fix buffer overflow in snd_pcm_chmap_print()

The size argument is wrong for one of the snprintf() calls in
snd_pcm_chmap_print(), allowing an overflow to happen (the user-provided
buffer may be written data up to 2x its actual size).

Seen in an user report here: http://trac.kodi.tv/ticket/15641
