xfrm: fix 'passing zero to ERR_PTR()' warning
Fix a static code checker warning: net/xfrm/xfrm_policy.c:1836 xfrm_resolve_and_create_bundle() warn: passing zero to 'ERR_PTR' xfrm_tmpl_resolve return 0 just means no xdst found, return NULL instead of passing zero to ERR_PTR. Fixes: d809ec895505 ("xfrm: do not assume that template resolving always returns xfrms") Signed-off-by: YueHaibing <yuehaibing@huawei.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
