[PATCH] xen/arm: add_to_physmap_one: Avoid to map mfn 0 if an error occurs
By default, the function add_to_physmap_one set mfn to 0. Some code paths that
result to an error, continue and the map the mfn 0 (valid on ARM) to the
slot given by the guest.
To fix the problem, return directly an error if sanity check has failed.
