libs: display: egl: avoid two vaDisplay instantiates

Browse source 
GstVaapiDisplayEGL is a wrapper of another GstVaapiDisplay, either X11
or Wayland. Nonetheless it created another vaDisplay for it, instead
of using the wrapped one.

This patch enables the reuse of the wrapped vaDisplay avoiding
instantiating two.
