[libvirt] [PATCH] util: Fix build with clang
When compiling with clang on Linux, it complains that "passing an
object that undergoes default argument promotion to 'va_start' has
undefined behavior". That is true according to the C standard,
although I couldn't find any mention about enum->int promotion (even
though it's a sensible one). The only fix I came up with was changing
the layer parameter to int so that it does not undergo any default
argument promotion.

Even though this is a build-breaker, I don't see anyone (or CI)
complaining about it, and the fix doesn't lok that nice, so...
