[libvirt] [PATCH] Fix uses of virFileMakePath.

[Laine Stump]

When I modified the use of virFileMakePath in my own code, I noticed
that it was checking for a return < 0 to indicate error, but I had
seen in virFileMakePath that it returns 0 for success, or the value of
errno on failure, and errno is usually (always?) >=0. Seeing incorrect
usage in one place, I investigated and found several others.
