[PATCH] scsi: Fix reference count leak in iscsi_boot_create_kobj.

[wu000273]

From: Qiushi Wu <wu000273@xxxxxxx>

kobject_init_and_add() should be handled when it return an error,
because kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Previous
commit "b8eb718348b8" fixed a similar problem. Thus replace calling
kfree() by calling kobject_put().
