xfrm: Convert xfrm_addr_cmp() to boolean xfrm_addr_equal().
All users of xfrm_addr_cmp() use its result as boolean. Introduce xfrm_addr_equal() (which is equal to !xfrm_addr_cmp()) and convert all users. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
