by XENMEM_decrease_reservation, it is checked by the hypervisor. In certain
circumstances (stack leak), the field could have an improper value, leading
to a fail of the hypercall.
Set it to 0 ("no addressing restriction") to avoid that.
Patch tested by Sam Fourman and haad@.
This should fix the rare "failed allocating DMA memory" encountered
under NetBSD dom0. Will ask for a pull-up.
