xen/arm: cpuerrata: Align a virtual address before unmap

After changes introduced by 9cc0618eb0 "xen/arm: mm: Sanity check any
update of Xen page tables" we are able to vmap/vunmap page aligned
addresses only.

So if we add a page address remainder to the mapped virtual address,
we have to mask it out before unmapping.
