From: Vincent Cheng <vincent.cheng...@renesas.com>
When a unicast master is no longer the best master, an UC_EV_UNSELECTED
event occurs for that unicast master entry. However, the sync/delay_response
contracts are not explicitly cancelled.
This patch updates unicast_client_state_changed() to send
CANCEL_UNICAST_TRANSMISSION to cancel sync/delay_response messages on
UC_EV_UNSELECTED event.
