There are two tiers of pending flush control, main controller and individual hardware block. Currently only the main controller of flush mask is reset to 0 but leave out some individual pending flush mask of particular hardware block keep previous value at clear_pending_flush(). Reset all individual hardware blocks flush mask to 0 to avoid individual hardware block be triggered accidentally.
