Bluetooth: fix possible info leak in bt_sock_recvmsg()
In case the socket is already shutting down, bt_sock_recvmsg() returns
with 0 without updating msg_namelen leading to net/socket.c leaking the
local, uninitialized sockaddr_storage variable to userland -- 128 bytes
of kernel stack memory.
Fix this by moving the msg_namelen assignment in front of the shutdown
test.
