[PATCH] net: tftpboot: clear timeout_count on every successful block

[Mikhail Kshevetskiy]

timeout_count is never reset once a tftpboot transfer has started. If for
whatever reason timeouts occur frequently, but the server keeps replying
nonetheless, the transfer may be needlessly aborted.

Reset timer_count on every successful block to avoid this situation.
