Patch 1/2 introduces support for AF_UNIX stream-oriented socket to
be passed as -netdev, and patch 2/2 fixes a minor issue I found while
trying to connect to an invalid path.
Stefano Brivio (2):
net: Allow also UNIX domain sockets to be used as -netdev socket
net: Don't ignore EINV
It has lower overhead compared to TCP, doesn't need a free port
and the adaptation is trivial.

Other errors are treated as failure by net_socket_connect_init(),
but if connect() returns EINVAL, we'll fail silently. Remove the
related exception.
