Remove unnecessary null checking on ViewRootImpl#mWindowAttribute
From static analysis, as ViewRootImpl#mWindowAttribute is now a final
object from CL[1] and the object is created when ViewRootImpl initialized
so the object reference should not be changed, it won't be necessary to do
the null check again for some code points.
