[libvirt] [PATCH] Avoid cast to unit64_t on 32bit platform

[Guido Günther]

Fixes compilation on 32bit platforms:

xen/xen_hypervisor.c: In function 'virXen_setvcpumap':
xen/xen_hypervisor.c:1785:35: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
xen/xen_hypervisor.c:1785:22: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
cc1: all warnings being treated as errors
