libztex: Start download sequence only after reading in the new firmware

Browse Source 
The download sequence starts with a reset command, which tells the board
that a new firmware is about to be downloaded. The board gets unhappy if
no new firmware is actually sent, so only send the reset command AFTER
the new firmware has actually been successfully read.
