Bail from drmmode_set_mode_major if it's called too early

That must be luck, DRI3 should be enabled by default anyway.

I can't seem to reproduce the problem. It looks like maybe crtc->enabled isn't
always initialized to FALSE in drmmode_xf86crtc_resize at this point (valgrind
doesn't complain about any access to uninitialized memory though).

Does this patch avoid the problem for you?
