Subject: [PATCH] evas/wayland_egl: Don't create EGLSurface for internal gl
 resource if we already have one in re->win.

EGL 1.4 spec Section 3.5.1: If there is already an
EGLSurface associated with win (as a result of a previous
eglCreateWindowSurface call), then an EGL_BAD_ALLOC error is
generated.

So that this eglCreateWindowSurface() will fail if the egl driver is
a strict conformance to the spec.
