drm/crtc: Remove duplicated ioctl code

Browse Source 
Make drm_mode_add_fb() call drm_mode_add_fb2() after converting its
args to the new internal format, instead of duplicating code.

Also picks up a lot more error checking, which the legacy modes
should pass after being converted to the new format.
