    libxl: initialise nr_dom_vcpus to fix 4a6070ea9
    
    Clang complains nr_dom_vcpus may be used uninitialised after
    4a6070ea9.
    
    The real issue is vinfo can be NULL and nr_dom_vcpus remains
    uninitialised if previous call fails.
    
    Initialise nr_dom_vcpus to 0 at the beginning of the loop to fix the
    issue.
