[libvirt] [PATCH 2/2] XML: Suppress printing "domain.xml" for parse errors on XML strings

[Peter Krempa]

Patch e81778d6184f1850a10eb661eb756b50421d5ac4 introduces printing
file name on XML errors. This corrects the URL string to be NULL and
therefore to print an error message not containing bogus filename
"domain.xml".

NULL is a valid parameter for the file name value, as the only usage is
for error handlers. Functions touching the value either in libxml2 or in
libvirt check this parameter for NULL and behave according to it.
