[965] Fix TTM relocation caching overzealousness.
The failure mode that was a available was: reloc 1 -> target_buf exec: PRESUMED_OFFSET wrong, buffer migrates, r1 entry updated. reloc 2 -> target_buf exec: suppose buffer migrates again. PRESUMED_OFFSET wrong. r2 entry updated. reloc 1 -> target_buf exec: suppose buffer doesn't migrate. PRESUMED_OFFSET right. no relocations performed. r1 has stale pointer at original location. Failures were reported with OGLconform's VBO test and SPECviewperf90, though I haven't confirmed that this fixes it.
