[PATCH 03/12] regulator: gpio-regulator: Fix logical error in for() loop

The cond-statement of this particular for() loop will always be
true as long as at least one voltage-shifting GPIO is present.
If it wasn't for the break below, we'd be stuck in a forever loop.
This patch inserts the correct cond-statement into the statement.
