usb: gadget: fastboot: improve download progress bar
When download is ongoing, if the actual size of one transfer is not the same as BYTES_PER_DOT, which will cause the dot won't print anymore. Then it will let the user thinking it is stuck, actually it is transfering without dot printed. So, improve the method to show the progress bar (print dot).
