Subject: [PATCH 8/9] xfrm: remove empty xfrmi_init_net

From: Li RongQing <lirongqing@...du.com>

Pointer members of an object with static storage duration, if not
explicitly initialized, will be initialized to a NULL pointer. The
net namespace API checks if this pointer is not NULL before using it,
it are safe to remove the function.
