xen/pciback: use resource_size()
Use resource_size function on resource object instead of explicit computation. The semantic patch that makes this output is available in scripts/coccinelle/api/resource_size.cocci. More information about semantic patching is available at http://coccinelle.lip6.fr/ Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
