virgl: pass whole GL scanout dimensionspull-spice-20160706-1

Spice client needs the whole GL texture dimension to be able to show a
scanout with a monitor offset (different than +0+0).

Furthermore, this fixes a crash when calling surface_{width,height}()
after dpy_gfx_replace_surface(con, NULL) was called in
virgl_cmd_set_scanout()
