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.
