"hf mf ekeyprn d" doesn't works properly (#904)

FIX: command "hf mf ekeyprn  d" doesn't use the correct offset to locate the A key in data[] array and record the 2 last bytes followed by 4 0x00 instead of the 6 good bytes (All the A keys are corrupted in file dumpkeys.bin). B keys are not affected.
