xen: arm: process XENMEM_add_to_physmap_range forwards not backwards.

Jan points out that processing the list backwards is rather counter intuitive
and that the effect of the hypercall can differ between forwards and backwards
processing (e.g. in the presence of duplicate idx or gpfn, which would be
unusual but as Jan says, users are a creative bunch)
