xen/arm: Drop reference on foreign page when guest_physmap_add_entry has failed

When a foreign page is added to the guest p2m, we take a reference on this page.
Currently if the mapping has failed when a leak a reference, this will result
to the guest will foreign guest will became a zombie as soon as it's destroyed.
