commit d65c357b398d3e0397a9282af6c55e24c6dbde4a

During a call to ecore_evas_show (using wayland_shm), we can avoid
erroneous calls to engine_setup code if we check surface validity.
NB: Short Version: Don't reassign surface if we don't need to.
NB: Prior to this, during a call to ecore_evas_show we would always
Reset the evas engine data (which was basically triggering code to
tear down and reconstruct all the engine internals including the
buffers and the swapper). By checking surface validity first, we can
potentially avoid all that teardown and reconstruction Thus resulting
in faster "show" speed.
