xen/grant-table: fix suspend for non-PV guests
Commit aa8532c32216ae07c3813b9aeb774517878a7573 (xen: refactor suspend
pre/post hooks) broke resuming PVHVM (auto-translated physmap) guests.
The gnttab_suspend() would clear the mapping for the grant table
frames, but the ->unmap_frames() call is only applicable to PV guests.
