net: appletalk: Fix device refcount leak in atrtr_create()
When updating an existing route entry in atrtr_create(), the old device reference was not being released before assigning the new device, leading to a device refcount leak. Fix this by calling dev_put() to release the old device reference before holding the new one. Fixes: c7f905f0f6d4 ("[ATALK]: Add missing dev_hold() to atrtr_create().")
