xen-gntdev: Use ballooned pages for grant mappings
Grant mappings cause the PFN<->MFN mapping to be lost on the pages used for the mapping. Instead of leaking memory, use pages that have already been ballooned out and so have no valid mapping. This removes the need for the bad-page leak workaround as pages are repopulated by the balloon driver.
