[PATCH 6/6] net: tftp: sanitize tftp block size, especially for TX

U-Boot does not support IP fragmentation on TX (and unless CONFIG_IP_DEFRAG is set, neither on RX). So the blocks we send must fit in a single ethernet packet. Currently, if tftpblocksize is set to something like 5000 and I tftpput a large enough file, U-Boot crashes because we overflow
