xfrm_user: return error pointer instead of NULL #2

[ Upstream commit c25463722509fef0ed630b271576a8c9a70236f3 ]

When dump_one_policy() returns an error, e.g. because of a too small
buffer to dump the whole xfrm policy, xfrm_policy_netlink() returns
NULL instead of an error pointer. But its caller expects an error
pointer and therefore continues to operate on a NULL skbuff.
