Sabrina Dubroca 13b32a7e54 Revert "xfrm: destroy xfrm_state synchronously on net exit path" ...

[ Upstream commit 2a198bbec6 ]

This reverts commit f75a2804da.

With all states (whether user or kern) removed from the hashtables
during deletion, there's no need for synchronous destruction of
states. xfrm6_tunnel states still need to have been destroyed (which
will be the case when its last user is deleted (not destroyed)) so
that xfrm6_tunnel_free_spi removes it from the per-netns hashtable
before the netns is destroyed.

This has the benefit of skipping one synchronize_rcu per state (in
__xfrm_state_destroy(sync=true)) when we exit a netns.
