power: qpnp-smbcharger: handle the regulator probe deferral properly 

Currently, if regulator_register() of smbcharger-external-otg
regulator returns an error (e.g. -EPROBE_DEFER),
regulator_unregister() is not called for smbcharger-boost-otg
regulator which got registered before that.

This causes problems during bootup later because of an invalid
regulator device being left registered indefinitely.

Fix this by unregistering the regulator that got registered
already when there is an error in registering the other.
