[RenderEngine] Do not cache protected EGLImage between runs.
Normally on a device the amount of protected memory is limited, however,
currently RenderEngine caches all generated EGLImage until layer is
destroyed, and hence eventually we run out of memory when trying to
create a protected EGLImage. This patch makes sure we unbind the buffer
and destroy the EGLImage once it's finished.
