    x86/hvm: change EOI exit bitmap helper parameter
    
    Change the last parameter of the update_eoi_exit_bitmap helper to be a
    set/clear boolean instead of a triggering field. This is already
    inline with how the function is implemented, and will allow deciding
    whether an exit is required by the higher layers that call into
    update_eoi_exit_bitmap. Note that the current behavior is not changed
    by this patch.
    
    No functional change intended.
