net: qrtr: Fix port ID for control messages

Browse Source 
[ Upstream commit ae068f561baa003d260475c3e441ca454b186726 ]

The port ID for control messages was uncorrectly set with broadcast
node ID value, causing message to be dropped on remote side since
not passing packet filtering (cb->dst_port != QRTR_PORT_CTRL).

Fixes: d27e77a3de ("net: qrtr: Reset the node and port ID of broadcast messages")
