Subject: [PATCH] fix(network): add errors and warnings when network interface
does not exist
End with error, or show a warning when nonexistent device is specified for network setup like
`ip=10.12.8.12::10.12.255.254:255.255.0.0:xk12:eth0:off`.
I've added the error only for `write-ifcfg.sh`, as I think no such setup should be written.
Resolves: #1712424
