intel: Don't mark front buffer dirty if we're only reading

When we call intel_prepare_render() from intelReadPixels(), we'll mark
the front buffer dirty.  That's silly, since we're only reading from it
and marking it dirty will cause us to copy from fake front to front
eventually.

Just clear the dirty flag after doing the read.
