====================
dst_cache: fix possible races

This series is inspired by various undisclosed syzbot
reports hinting at corruptions in dst_cache structures.

It seems at least four users of dst_cache are racy against
BH reentrancy.

Last patch is adding a DEBUG_NET check to catch future misuses.
