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.
