[PATCH] KWin: Fix memory leak in Workspace::rootStackingOrder

[Kelvie Wong <kelvie@xxxxxxxx>]

This would leak memory every time compositing takes place, and really adds up
over time (I get about 500k/minute with a bunch of windows open).  KWin stays at
a lean 23MB after this patch.

This was introduced by r800581.
