driver core: Delete an unnecessary check before the function call "put_device"

commit 5f0163a5ee9cc7c59751768bdfd94a73186debba upstream.

The put_device() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
