dix: Skip more code in SetRootClip for ROOT_CLIP_INPUT_ONLY

Browse source 
Despite e957a2e5dd ("dix: Add hybrid full-size/empty-clip mode to
SetRootClip"), I was still seeing all X11 client windows flashing when
the root window size changes with rootless Xwayland (e.g. due to
hotplugging a monitor).

Skipping this code for ROOT_CLIP_INPUT_ONLY fixes the issue for me.

(cherry picked from commit f778b56a74)
