[alsa-lib][PATCH v3 4/4] pcm: plug: add SND_PCM_FORMAT_{S, U}20 to linear_preferred_formats

["Maciej S. Szmigiero" <mail@maciej.szmigiero.name>]

This commit adds the recently added formats SND_PCM_FORMAT_{S,U}20 to
the linear_preferred_formats array in pcm_plug.
Let's give them lower priority than more standard S24 formats but a higher
priority than less typical 3-byte versions.
