ipmi_ssif: fix unexpected driver unregister warning
If platform_driver_register() fails from init_ipmi_ssif(),
platform_driver_unregister() called unconditionally will
trigger following warning,
ipmi_ssif: Unable to register driver: -12
------------[ cut here ]------------
Unexpected driver unregister!
WARNING: CPU: 1 PID: 6305 at drivers/base/driver.c:193 driver_unregister+0x60/0x70 drivers/base/driver.c:193
Fix it by adding platform_registered variable, only unregister platform
driver when it is already successfully registered.
