f2fs: in prior to issue big discard Keep issuing big size discard in prior instead of the one with random size, so that we expect that it will help to: - be quick to recycle unused large space in flash storage device. - give a chance for a) wait to merge small piece discards into bigger one, or b) avoid issuing discards while they have being reallocated by SSR.
