Subject: [PATCH 1/1 net-2.6.26] [XFRM]: Compilation warnings in xfrm_user.c.

When CONFIG_SECURITY_NETWORK_XFRM is undefined the following warnings appears:
net/xfrm/xfrm_user.c: In function 'xfrm_add_pol_expire':
net/xfrm/xfrm_user.c:1576: warning: 'ctx' may be used uninitialized in this function
net/xfrm/xfrm_user.c: In function 'xfrm_get_policy':
net/xfrm/xfrm_user.c:1340: warning: 'ctx' may be used uninitialized in this function
(security_xfrm_policy_alloc is noop for the case).

It seems that they are result of the commit
03e1ad7b5d871d4189b1da3125c2f12d1b5f7d0b
