Desmond Cheong Zhi Xi c20d8c1974 Bluetooth: fix init and cleanup of sco_conn.timeout_work 
[ Upstream commit 49d8a56064 ]

Before freeing struct sco_conn, all delayed timeout work should be
cancelled. Otherwise, sco_sock_timeout could potentially use the
sco_conn after it has been freed.

Additionally, sco_conn.timeout_work should be initialized when the
connection is allocated, not when the channel is added. This is
because an sco_conn can create channels with multiple sockets over its
lifetime, which happens if sockets are released but the connection
isn't deleted.

Fixes: ba316be1b6 ("Bluetooth: schedule SCO timeouts with delayed_work")
