[libvirt] [PATCH] virfile: Fix virFileExists commentary

[Erik Skultety]

Arguably though, function returning only on success is a very
interesting, although quite impractical concept. Also, the errno isn't
and shouldn't be preserved in this case, since the errno can be directly
fed to the virReportSystemError.
