zsmalloc: fix zs_init cpu notifier error handling
Mahendran Ganesh reported that zpool-enabled zsmalloc should not call
zpool_unregister_driver() from zs_init() if cpu notifier registration has
failed, because error handling is performed before we register the driver
via zpool_register_driver() call.
Factor out cpu notifier registration and unregistration code and fix
zs_init() error handling.
