Commit da546e0 (dpif: Allow execute to modify the packet.) introduced
a bug by subtracting the zero-value ofpbuf size by "sizeof(struct
nlattr)" and assigning the result back to the ofpbuf size. This bug
causes the ovs-assert failure in facet_push_stats().
This commit fixes the bug by assigning the right value to the ofpbuf
size.
