Subject: [PATCH 2/4] xfrm: remove stray synchronize_rcu from xfrm_init

From: Florian Westphal <fw@...len.de>

This function is called during boot, from ipv4 stack, there is no need
to set the pointer to NULL (static storage duration, so already NULL).

No need for the synchronize_rcu either.  Remove both.
