net: ieee802154: return -EINVAL for unknown addr type
commit 30393181fdbc1608cc683b4ee99dcce05ffcc8c7 upstream.
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.
