    pmap: Degrade pmap_page_set_attr*() into a no-op on same attribute

    For 32-bit arm, move the no-op test that was already in place at start
    of the function so that it stays first even if the '#if 0' block around
    the call to sf_buf_invalidate_cache() is uncommented at some point (if
    ever).
