serial: sunsab: Fix error handling in sunsab_init()

[ Upstream commit 1a6ec673fb627c26e2267ca0a03849f91dbd9b40 ]

The sunsab_init() returns the platform_driver_register() directly without
checking its return value, if platform_driver_register() failed, the
allocated sunsab_ports is leaked.
Fix by free sunsab_ports and set it to NULL when platform_driver_register()
failed.
