xen: remove XEN_GUEST_HANDLE(ulong)

Having both this handle (always unsigned long) and
XEN_GUEST_HANDLE(xen_ulong_t) (unsigned long on x86 and explicit size
of ARM) is confusing and error prone.

Replace the two remaining uses of the ulong handle, in grant set and
x86 set_gdt hypercalls, with xen_ulong_t.

This correctly sizes the grant frame entry as 64 bit on ARM but
leaves it as unsigned long on x86 (therefore no intended change on
x86). Likewise in set_gdt there is no actual change.
