serial: sunsab: Fix error handling in sunsab_init()
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.
Fixes: c4d37215a824 ("[SERIAL] sunsab: Convert to of_driver framework.")
