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.
