wct4xxp: Update span-local struct with timing info

dahdi_tool was incorrectly reporting all spans to be in local timing
mode. This is because the driver tracks which span it's timing syncs to,
within the card local struct "wc". We have to manually go through and
copy timing updates to the span local structs because this is what
dahdi_tool actually reads.
