check_hpjd patch.

-----------------
We have a few machines with jd 610 cards that false flag a printer as offline ("line 1") even if there is no other error
and the display status shows "READY".
These devices may or may not behave wrong.
For example, i had a printer that was wrong until i removed and reinserted the paper tray - that made the error go away.

This patch provides a fix for these devices:
Added cmdline arg (-N, --flawcorrection).
