[PATCH] ACPI: sysfs: Fix reference count leak in acpi_sysfs_add_hotplug_profile.

[wu000273]

From: Qiushi Wu <wu000...@umn.edu>

kobject_init_and_add() takes reference even when it fails.
Thus, when kobject_init_and_add() returns an error,
kobject_put() must be called to properly clean up the kobject.

Fixes: 3f8055c35836 ("ACPI / hotplug: Introduce user space interface for 
hotplug profiles")
