[PATCH 2/3] Avoid compiler warnings about int -> void * casts

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

GCC is a little confused about the cast of beginthread/beginthreadex
from unsigned long -> void *. Go via an intermediate variable avoids
the bogus warning, and makes the code a little cleaner

* src/util/threads-win32.c: Avoid compiler warning in cast
