dfu:ext4:fix Fix DFU upload functionality 

For the first eMMC read of data for upload, use the "large" dfu_buf (now
configurable) instead of usb request buffer allocated at composite layer
(which is 4KiB) [*].

For eMMC the whole file is read, which usually is larger than the buffer [*]
provided with usb request.
