regulator: Remove unneded check for regulator supply
The regulator_resolve_supply() function checks if a supply has been
associated with a regulator to avoid enabling it if that is not the
case.
But the supply was already looked up with regulator_resolve_supply()
and set with set_supply() before the check and both return on error.
So the fact that this statement has been reached means that neither
of them failed and a supply must be associated with the regulator.
