Improved hf iclass legrec speed

Browse source 
Improved the speed of hficlass legrec from 7200 keys / hrs to 17800 keys / hr by removing the need to drop the field and re-select, re-authenticate with the card at every loop.
Re-select and re-authenticate will still happen if there's a read error and a loop needs to be repeated.
