regulator: core: fix resource leak in regulator_register()
I got some resource leak reports while doing fault injection test:

After calling regulator_resolve_supply(), the 'rdev->supply' is set by set_supply(), after this set, in the error path, the resources need be released, so call regulator_put() to avoid the leaks.
