[v3,0/2] xen/gnttab: reduce size of struct active_grant_entry

While looking at the grant table code I thought it should be possible
to have a smaller struct active_grant_entry. This approach should only
hit transitive grants with some negative performance effect, "normal"
grants should be not affected.
