regulator: core: Fix rdev reference leak in regulator_resolve_supply()

regulator_resolve_supply() takes a reference on the looked-up regulator
with regulator_dev_lookup(), but when the supply resolves to the
regulator itself that reference is never dropped: it leaks on the early
return and is lost as well when r is replaced with the dummy regulator.

Release the reference before handling the self-referent case.
