can: netlink: can_changelink(): rename tdc_mask into fd_tdc_flag_provided
The only purpose of the tdc_mask variable is to check whether or not any tdc flags (CAN_CTRLMODE_TDC_{AUTO,MANUAL}) were provided. At this point, the actual value of the flags do no matter any more because these can be deduced from some other information. Rename the tdc_mask variable into fd_tdc_flag_provided to make this more explicit. Note that the fd_ prefix is added in preparation of the introduction of CAN XL.
