Vlad Zagorodniy 688d946ffb [libkwineffects] Gracefully release previous window pixmap
Summary:
If the cross fade animation is cancelled, we are not gracefully
unreference the previous window pixmap.

This change addresses that issue by using RAII approach to
reference/unreference the previous window pixmap.

Test Plan: Manually. The Maximize and the Morphing Popups effect still work.
