Indentation of 'return' is too deep

This should use virReportSystemError.

This should use virReportSystemError too, and propagate the error.

Likewise. Also it uses NULL 'entry' var rather than 'base' in the message args.

I'm going to send a followup with these fixes for review, which also centralizes the error cleanup code.
