[PULL 29/35] ui/console: fix texture leak when calling surface_gl_create_texture()

[Gerd Hoffmann]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Make surface_gl_create_texture() idempotent: if the surface is already
bound to a texture, do not create a new one.

This fixes texture leaks when there are multiple DBus listeners, for
example.
