Michel Dänzer 1c3e51daba xfree86/modes: Bail from xf86RotateRedisplay if pScreen->root is NULL 
Avoids a crash in xf86RotatePrepare -> DamageRegister during
CreateScreenResources if rotation or another transform is configured for
any connected RandR output in xorg.conf. The generic rotation/transform
code generally can't work without the root window currently.

Closes: https://gitlab.freedesktop.org/xorg/xserver/issues/969
Fixes: 094f42cdfe "xfree86/modes: Call xf86RotateRedisplay from
                     xf86CrtcRotate"
