E_Alpha_Mask_Rect: Do not force update if pixmap of ec does not have buffer

eglImage is destroyed in e_comp_object_native_surface_set(FALSE)
and the force update fails becuase the pixmap of ec does not have a buffer.
so the frame of ec is in a show state, but since the buffer of ec is not set,
garbage may be displayed on the screen.
