Input: wm97xx - make .remove() obviously always return 0

wm97xx_remove() returns zero unconditionally. To prepare changing the
prototype for platform remove callbacks to return void, make it explicit
that wm97xx_mfd_remove() always returns zero.

The prototype for wm97xx_remove cannot be changed, as it's also used as
a plain device remove callback.
