P2P: Send P2P-DEVICE-FOUND event on peer changing device name

This is to handle the case when peer changes device name and same needs
to be updated to upper layers by P2P-DEVICE-FOUND event. It is similar
to the case when a peer changes wfd_subelems and P2P-DEVICE-FOUND event
goes to upper layers.
