QRhiGles2: Skip GL cleanup on context loss

Browse Source 
We are getting errors such as

  WebGL: INVALID_OPERATION: delete: object does not
  belong to this context

Normally, QRhiGles2::destroy() should delete/free all
GL resources. However if the GL context is lost then
there is not much we can do.

Task-number: QTBUG-120138
