Bluetooth: ISO: Pass BIG encryption info through QoS
This enables a broadcast sink to be informed if the PA
it has synced with is associated with an encrypted BIG,
by retrieving the socket QoS and checking the encryption
field.
After PA sync has been successfully established and the
first BIGInfo advertising report is received, a new hcon
is added and notified to the ISO layer. The ISO layer
sets the encryption field of the socket and hcon QoS
according to the encryption parameter of the BIGInfo
advertising report event.
After that, the userspace is woken up, and the QoS of the
new PA sync socket can be read, to inspect the encryption
field and follow up accordingly.
