[PATCH v2 21/25] ASoC: renesas: msiof: Remove redundant period constraint

[phucduc.bui at gmail.com]

From: bui duc phuc <phucduc.bui at gmail.com>

snd_pcm_hw_constraint_integer() is already called by
snd_dmaengine_pcm_open(). Calling it again in msiof_open() is
unnecessary, as the constraint is already applied and the second
call returns 0.

Remove the redundant constraint call.

Changes in v2: 
 - Remove redundant integer constraints already applied by 
   snd_dmaengine_pcm_open().
