anv/allocator: Use VG_NOACCESS_WRITE in anv_bo_pool_free
Previously, we were relying on the fact that VALGRIND_MEMPOOL_FREE came later on in the function to prevent "link->bo = bo" from causing an invalid write. However, in the case where the size requested by the user is very small (less than sizeof(struct anv_bo)), this isn't sufficient. Instead, we should call VALGRIND_MEMPOOL_FREE early and then use VG_NOACCESS_WRITE. We do, however, have to call VALGRIND_MEMPOOL_FREE after reading bo_in because it may be stored in the bo itself.
