This was actually intentional when I created these helpers, since IMHO
the string concatenation between the caller supplied error message and
the virErrorMsg funtion leads to fugly error messages. So the intent
was that these helper macros would provide the complete error message
that's relevant to their usage, and ignore virErrorMsg.

IOW, I don't think adding a 'invalid argument: ' prefix to these
helper macros is particularly useful.
