cpu topology: consider sysfs_create_group return value
Take return value of sysfs_create_group() into account. That function got
called in case of CPU_ONLINE notification. Since callbacks are not allowed
to fail on CPU_ONLINE notification do the sysfs group creation on
CPU_UP_PREPARE notification.
Also remember if creation succeeded in a bitmask. So it's possible to know
whether it's legal to call sysfs_remove_group or not.
In addition some other minor stuff:
- since CPU_UP_PREPARE might fail add CPU_UP_CANCELED handling as well.
- use hotcpu_notifier instead of register_hotcpu_notifier.
- #ifdef code that isn't needed in the !CONFIG_HOTPLUG_CPU case.
