intel_mode_from_pipe_config() fills in a mode structure from the CRTC state that was read out of the hardware, but does not set the .crtc_clock field (it only sets the .clock). This causes the subsequent call to drm_calc_timestamping_constants() to complain with messages like "*ERROR* crtc 21: Can't calculate constants, dotclock = 0!" Ensuring .crtc_clock is set as well eliminates this error.
