fixed Check MakeCurrent error for cairo gles

[Title] fixed Check makeCurrent error for cairo gles
[Issue#] N/A
[Problem] Check MakeCurrent error happens in DDK when destroying ImageBuffer
[Cause] Because we don't call makeCurrent for gl surface, some gl calls could remain although the context already gone
[Solution] fixed to call glFlush to make sure all gl calls have been committed before destroying pixmaps
