[libvirt] [PATCH] build: drop unused variable



Compilation for mingw failed:

../../src/util/virutil.c: In function 'virGetWin32DirectoryRoot':
../../src/util/virutil.c:1094:9: error: unused variable 'ret' [-Werror=unused-variable]

* src/util/virutil.c (virGetWin32DirectoryRoot): Silence compiler
warning.

Compilation still fails in the tests directory, due to the use of
fprintf(stderr, "%zu", size_t); I'm still debating whether I can
get it fixed in gnulib and take the risk of a gnulib backport before
rc2, or whether we'll have to come up with some other less-invasive
workaround.
