bus: sunxi-rsb: Fix error handling in sunxi_rsb_init() 



[ Upstream commit f71eaf2708be7831428eacae7db25d8ec6b8b4c5 ]

The sunxi_rsb_init() returns the platform_driver_register() directly
without checking its return value, if platform_driver_register() failed,
the sunxi_rsb_bus is not unregistered.
Fix by unregister sunxi_rsb_bus when platform_driver_register() failed.
