    xen: arm re-order assignments in mfn_to_xen_entry()
    
    Shuffle lines around so that the assignments in mfn_to_xen_entry()
    occur in the same order as the bits are declared in lpae_pt_t.
    This makes it easier to see which ones are never given a value.
    No change in behaviour.
    
    Also fix a minor comment typo.
