Bluetooth: hci_conn: Fix updating ISO QoS PHY
BT_ISO_QOS has different semantics when it comes to QoS PHY as it uses
0x00 to disable a direction but that value is invalid over HCI and
sockets using DEFER_SETUP to connect may attempt to use hci_bind_cis
multiple times in order to detect if the parameters have changed, so to
fix the code will now just mirror the PHY for the parameters of
HCI_OP_LE_SET_CIG_PARAMS and will not update the PHY of the socket
leaving it disabled.
Fixes: 26afbd826ee32 ("Bluetooth: Add initial implementation of CIS connections")
