    compat.h: drop COMPAT_HANDLE_PARAM()
    
    The need for 8844ed299a ("x86/dmop: Fix compat_dm_op() ABI") has made
    clear that its presence is actively dangerous. At the hypercall entry
    points XEN_GUEST_HANDLE_PARAM() should be used anyway (regardless of
    whether these are native or compat entry points), and passing around
    handles internally shouldn't use their compat representation either.
