net: qrtr: Fix passing invalid reference to qrtr_local_enqueue()

Once the traversal of the list is completed with list_for_each_entry(),
the iterator (node) will point to an invalid object. So passing this to
qrtr_local_enqueue() which is outside of the iterator block is erroneous
eventhough the object is not used.

So fix this by passing NULL to qrtr_local_enqueue().
