When the FD is turned off through the netlink interface, the value
still remain in struct can_tdc and are displayed despite of the
feature being disabled.
This patch clears priv->tdc whenever FD is set to off. This way, the
TDC variables are not displayed anymore.

Hi Marc,
I would suggest to squash that into commit 5eb2cd8e2ded ("can:
netlink: add interface for CAN-FD Transmitter Delay Compensation
(TDC)").
