evas-wayland-egl: Fix the unnecessary renewal of the engine window.

evas-wayland-egl: Fix the unnecessary renewal of the engine window.

Summary:
As we do not set the ob->info->info.win variable anymore inside
Ecore_Evas (old code that was removed), we can omment out the line.
This line was causing unnecessary renewal of the engine window (thus
causing flickering when rotation was applied).

@fix

Test Plan: Rotate or Resize the window on wayland-egl.
