Haimin Zhang 3c9a75b3d2 net/ieee802154: fix uninit value bug in dgram_sendmsg
[ Upstream commit 94160108a70c8af17fa1484a37e05181c0e094af ]

There is uninit value bug in dgram_sendmsg function in
net/ieee802154/socket.c when the length of valid data pointed by the
msg->msg_name isn't verified.

We introducing a helper function ieee802154_sockaddr_check_size to
check namelen. First we check there is addr_type in ieee802154_addr_sa.
Then, we check namelen according to addr_type.

Also fixed in raw_bind, dgram_bind, dgram_connect.
