power: qpnp-qnovo5: Revoke vote to disable CP upon USB disconnect 



Once userspace enables "standalone" mode, the charge pump will remain
disabled until userspace disables it via a zero-write to that parameter.
Fix this so that the charge pump may get re-enabled upon USB reinsertion
following a disconnection.
