regulator: core: Fix memory leak in regulator_resolve_supply()
The regulator_resolve_supply() function calls set_supply() which in turn calls create_regulator() to allocate a supply regulator. If an error occurs after set_supply() succeeded, the allocated regulator has to be freed before propagating the error code.
