i965: Don't do the temporary-and-blit-copy for INVALIDATE_RANGE maps.
We definitely want to fall through to the unsynchronized map case, instead of wasting bandwidth on a copy. Prevents a -43.2407% +/- 1.06113% (n=49) performance regression on aa10perf when teaching glamor to provide the GL_INVALIDATE_RANGE_BIT information. This is a performance fix, which I usually wouldn't cherry-pick to stable. But this was really was just a bug in the code, its presence would discourage developers from giving us the best information they can, and I think we've got fairly high confidence in the unsynchronized map path already.
