brw_bo_alloc may round up our allocation size to the next bucket size.
In this case, we would malloc a shadow buffer that was the original
intended size, but use bo->size (the larger size) for all of our checks.

This could cause us to run off the end of the shadow buffer.

v2: Actually use the new BO size (caught by Lionel)
