[libvirt] [PATCH] util: fix va_start usage bug

[Eric Blake]

Detected by clang.  POSIX requires that the second argument to
va_start be the name of the last variable; and in some implementations,
passing *path instead of path would dereference bogus memory instead
of pulling arguments off the stack.

* src/util/util.c (virBuildPathInternal): Use correct argument to
va_start.

I think this falls under the trivial rule, as it silences a
compiler warning and is a one-line fix of a real bug, so I pushed it.
