intel: Call intel_prepare_render() in intelMakeCurrent()

This restores old behaviour, where we end up doing a DRI2GetBuffers()
call from intelMakeCurrent().  The idea was that we could do this
lazily, just before we start rendering.  However, if we don't do the
DRI2GetBuffers() round-trip we don't get the drawable size and higher
level mesa ends up short-cutting a number of GL calls, such as glClear().
