Sergey Senozhatsky 2f57d4ef53 UPSTREAM: zsmalloc: fix zs_init cpu notifier error handling 
(cherry-pick from commit b1b00a5b8a6cf32e3973507decf1216709b55072)

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.

Bug: 25951511
