vol-clone reports out of memory error with disk type on ppc64. Currently, wbytes is defined as size_t type (8 bytes), but args's value in ioctl(fd, args..) in kernel is int (4 bytes). This makes wbytes 2^32 times larger, causing an out of memory error. This patch changes size_t to int to synchronize with kernel.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
