  1. net_class: catch syscall.EINVAL and better handle read errors 

    prometheus#483 introduced a bug
that terminates attribute reading when the returned error is
syscall.Errno, which is what util.SysReadFile() will typically
return. Handle that case specifically.

While doing that pull the error checking into
ParseNetClassAttribute() for clarity and to allow external
callers to handle errors correctly.
