Don't set modes before RADEONWindowExposures_oneshot is called
The root window contents may be undefined before that, so we don't want
to show anything yet.
Fixes a crash on startup with rotation and virtual resolution set in
xorg.conf.
Bugzilla: https://bugs.freedesktop.org/100276
Fixes: cc9d6b7db9c2 ("Move DPMS check from radeon_scanout_do_update to
radeon_scanout_flip")
