Bluetooth: RFCOMM - Fix missing msg_namelen update in rfcomm_sock_recvmsg()
[ Upstream commit e11e0455c0d7d3d62276a0c55d9dfbc16779d691 ]
If RFCOMM_DEFER_SETUP is set in the flags, rfcomm_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_stream_recvmsg().
