[PATCH] ASoC: fsl_sai: Add missing return 0 in remove()

[Nicolin Chen]

Build warning being reported:
    sound/soc/fsl/fsl_sai.c: In function 'fsl_sai_remove':
    sound/soc/fsl/fsl_sai.c:921:1: warning: no return statement in
    function returning non-void [-Wreturn-type]

So this patch just adds a "return 0" to fix it.

Fixes: 812ad463e089 ("ASoC: fsl_sai: Add support for runtime pm")
