Set ec->explicit_sync_surface to null when it destroyed

 - If client try to create only explicit_surface_sync after
 destroying its old one while ec is retained,
 the creation will be failed because ec->explicit_surface_sync
 was not initialized to NULL.

 - This problem cannot occur in normal EGL client,
   but can occur in Vulkan.
