fs: configfs: don't return anything from drop_link
Documentation/filesystems/configfs/configfs.txt says: "When unlink(2) is called on the symbolic link, the source item is notified via the ->drop_link() method. Like the ->drop_item() method, this is a void function and cannot return failure." The ->drop_item() is indeed a void function, the ->drop_link() is actually not. This, together with the fact that the value of ->drop_link() is silently ignored suggests, that it is the ->drop_link() return type that should be corrected and changed to void. This patch changes drop_link() signature and all its users.
