Log Message:
Switch to dynamically-sized grant tables, available since Xen-3.1.0.
This removes a hard limit that would prevent a guest from running with more
than 7 virtual network interface.
If running on a hypervisor that doesn't support GNTTABOP_query_size, fall back
to a 4-pages grant table, so this change is backward-compatible.
