SurfaceView: Remove dead code

While debugging SurfaceView transaction usage I noticed this
code was unconditionally dead. Notice the else statement
only contains the single if statement within, so it could
be written as else-if. But then notice the condition of this
rewritten else-if is contained within the original if and
so it can never be entered.

Test: Existing tests pass
