The structure "ieee802154_addr_sa" need to fit into the u8 sa_data[14]
from struct sockaddr, because there is a casting of "struct sockaddr" and
"struct ieee802154_sockaddr".
I tested a compiling with a 32 bit system and detected that the "struct
ieee802154_sockaddr", which contains the ieee802154_addr_sa structure, has a
size of 20 bytes. The "struct sockaddr" has a size of 16 bytes. This doesn't
fit together and some buffers are overflows. This patch changes the
"addr_type" type definition from "int" to "u8". After this change it will be
fits together.
