    Fix a set but not used warning in the arm64 pmap
    
    In pmap_ts_referenced we read the virtual address from pv->pv_va,
    but then continue to use the pv struct to get the same value later
    in the function.
    
    Use the virtual address value we initially read rather than loading
    from the pv struct each time.
