Log:
wct4xxp: Bug in timing cable with different span density cards

The logic loops through the static cards[] array to determine timing,
    but the subloop was based off the current card's numspans member.
    This could cause a null dereference in the case where two cards of
    different span densities were connected via timing cables.
