e_hwc_window: fix problem that cursor window is freed even if it is displayed

buffer_ref of commit data can be changed to null when client destroy wl_buffer.
the problem is occurred when client destroy wl_buffer between commit and
commit_handler.

this patch use cursor info of the commit_data  instead buffer_ref for checking
whether the commit_data enable/disable display.
