[PATCH] regulator: Fix return code from regulator_disable_deferred()

[PATCH] regulator: Fix return code from regulator_disable_deferred()

[Mark Brown]

schedule_delayed_work() returns a bool indicating if the work was already
queued when it succeeds so we need to squash a true down to zero.

I'll queue this up along with the addition of the call in ASoC - please
say if this is a problem.
