Bluetooth: SCO - Fix missing msg_namelen update in sco_sock_recvmsg()
If the socket is in state BT_CONNECT2 and BT_SK_DEFER_SETUP is set in
the flags, sco_sock_recvmsg() returns early with 0 without updating the
possibly set msg_namelen member. This, in turn, leads to a 128 byte
kernel stack leak in net/socket.c.
Fix this by updating msg_namelen in this case. For all other cases it
will be handled in bt_sock_recvmsg().
