[PATCH] ALSA: sound: Increase max size of components field

[Maciej Strozek <mstrozek@opensource.cirrus.com>]

The components field of snd_card can run out of space in new systems which
use many audio devices, hence increase its size to 256 bytes.

Along with this change, bump the CTL protocol version to 2.0.10
