[PATCH 2/2] ALSA: sound/pci: add const to snd_ratnum structures

[Bhumika Goyal <bhumirks@gmail.com>]

Declare snd_ratnum structures as const as their reference is only
stored in the rate field of a snd_pcm_hw_constraint_ratnums structure.
This field is of type const, so snd_ratnum structures can be made const.
