[kvm-unit-tests PATCH] lib: use an argument which doesn't require default argument promotion

[Bill Wendling <morbo@xxxxxxxxxx>]

Clang warns that passing an object that undergoes default argument
promotion to "va_start" is undefined behavior:

lib/report.c:106:15: error: passing an object that undergoes default
argument promotion to 'va_start' has undefined behavior
[-Werror,-Wvarargs]
        va_start(va, pass);

Using an "unsigned" type removes the need for argument promotion.
