[PATCH] lightnvm: pblk: Fix reference count leak in pblk_sysfs_init.

[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: a4bd217b4326 ("lightnvm: physical block device (pblk) target")
