pcm: Fix channel map query when there are lots of maps
On most HDA Intel HDMI devices, the channel map list is approx. 500 ints
in size, making the 256-sized buffer used by
snd_pcm_query_chmaps_from_hw() too small and causing the query to fail
(NULL result to caller, ENOMEM).
Bump the buffer size to 2048 ints.
