[U-Boot] [PATCH] test: dfu: script: wrong md5sum on nand partitions

[Heiko Schocher]

when uplaoding a file, at least from a nand partition, the complete
mtd nand partition size is transferred. This leads in a wrong md5sum
as the filesize is different between the downloaded file and the
uploaded file. Limit the uploaded filesize to the downloaded
fixes this.

Tested this on the siemens boards, with current ml I get:

Init script for generating data necessary for DFU test script OK
=========================================================================================
DFU EP0 transmission test program
Trouble shoot -> disable DBG (even the KERN_DEBUG) in the UDC driver
@ -> TRATS2 # dfu 0 mmc 0
 =========================================================================================
File: dat_960.img
TX: md5sum:2947e8f573bc34ba3791f991bd2da869
RX: md5sum:cde0b2024d8ddb55eee9d4b51264ad67
    -------> FAILED

with this patch:
