No changes, just remove wxSplitterWindow::{Set,Get}NeedUpdating().

GetNeedUpdating() was never used at all while SetNeedUpdating() was used only
once while m_needUpdating variable was being changed directly in other places
making the code difficult to follow.

Just use the member variable directly and remove the accessors.
