net: ieee802154: return -EINVAL for unknown addr type
This patch adds handling to return -EINVAL for an unknown addr type. The
current behaviour is to return 0 as successful but the size of an
unknown addr type is not defined and should return an error like -EINVAL.
Fixes: 94160108a70c ("net/ieee802154: fix uninit value bug in dgram_sendmsg")
