needs_establish_peer_ has been used to skip actual estalishing a surface
texture peer based on many conditions. Not all places that modify
actually checks all these conditions so there are bound to be some bugs.

This CL aims to tease out all these different conditions and put them in
a single function EstablishSurfaceTexturePeerIfNeeded. This function
should be called any time these conditions are changed. Makes for much
saner reading.
