Bluetooth: hci_conn: Fix CIS connection dst_type handling
hci_connect_cis and iso_connect_cis call hci_bind_cis inconsistently
with dst_type being either ISO socket address type or the HCI type, but
these values cannot be mixed like this. Fix this by using only the HCI
type.
CIS connection dst_type was also not initialized in hci_bind_cis, even
though it is used in hci_conn_hash_lookup_cis to find existing
connections. Set the value in hci_bind_cis, so that existing CIS
connections are found e.g. when doing deferred socket connections, also
when dst_type is not 0 (ADDR_LE_DEV_PUBLIC).
Fixes: 26afbd826ee3 ("Bluetooth: Add initial implementation of CIS connections")
