tests: qemuxml2xml: Avoid crash when processing an XML that fails to parse

Browse Source 
Failure to parse a XML that was not supposed to fail would result into a
crash in the test suite as the vcpu bitmap would not be filled prior to
the active XML->XML test.

Skip formatting of the vcpu snippet in the fake status XML formatter in
such case to avoid the crash. The test would fail anyways.
