This is reporting an error without returning an error code, so the
caller will still see success.

Again, reporting an error while returning success.

This is likely blowing away a previously reported error.

No return status at all - this function likely shouldn't even
exist. Should be replaced with direct calls to VIR_FORCE_CLOSE
and VIR_CLOSE as appropriate, returning correct error codes
if it wants to handle close failures.

Reporting errors while returning success.
