  Fixed crash if initialization of EGL failed but was tried again later.
  
  The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
  uninitialized data structure if loading the library first failed. A later try to
  use EGL then skipped initialization and assumed it was previously successful
  because the data structure now already existed. This led to at least one crash
  in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
  dereferenced to make a call to eglBindAPI().
