Simplify hovering pointer condition

The hovering pointers are already getting cleared earlier in the
function (the call is 'tempTouchState.clearHoveringPointers();').

Therefore, the code path for "removeHoveringPointer" in response to
ACTION_HOVER_EXIT is never hit.

In this CL, we simplify this condition for clarity.
