usb: gadget: fastboot: improve download progress bar

Browse source 
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).
