Bail out everytime when mmc_regulator_get_supply() returns an errno, not only
when probing gets deferred. This is currently a no-op, because this function
only returns -EPROBE_DEFER or 0 right now. But if it will throw another error
somewhen, it will be for a reason. (This still doesn't change that getting
regulators is optional, so 0 can still mean no regulators found). So, let us a)
be future proof and b) have driver code which is easier to understand.
