    xen/arm32: mm: Rework is_xen_heap_page to avoid nameclash
   
    The arm32 version of the function is_xen_heap_page currently define a
    variable _mfn. This will lead to a compiler when use typesafe MFN in a
    follow-up patch:
   
    called object '_mfn' is not a function or function pointer
   
    Fix it by renaming the local variable _mfn to mfn_.
