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.
