    mesa: add bounds checking to eliminate buffer overrun

    Decompressing ETC2 textures was causing intermitent segfault
    by copying resulting 4x4 texel block to the destination texture
    regardless of the size of the destination texture. Issue found
    via application crash in GLBenchmark 3.0's Manhattan test.

    v2: add more detail comment. Compute limit outside inner loops.
    v3: add bugzilla reference
    v4: Correct cc syntax in commit log
    v5: really grab the right patch
