Input: synaptics-rmi4 - unregister function handlers on physical driver registration failure
If rmi_register_physical_driver() fails, the current error path
unregisters only the RMI bus. The function handlers registered
earlier remain registered with the driver core.
Add a separate error path to unregister the function handlers
before unregistering the bus in this failure case.
