fdo patch to free egl images

My understanding of the EGL image management in FDO is somewhat limited, but I believe that EGL images are being leaked when destroying webkit views. 

In my application I regularly call webkit_web_view_backend_new; this happens a lot because I create many separate webkit views and release them when no longer needed.

All EGL images that are consumed by the client (my code) are returned to FDO prior to webkit.view un-referencing using the wpe_view_backend_exportable_fdo_dispatch_frame_complete and wpe_view_backend_exportable_fdo_egl_dispatch_release_exported_image functions.


I notice that memory is consumed but not freed and upon investigation I found that EGL images were leaking.

The attached patch corrected my application and I'm submitting it for help here.
Thanks!
