xfrm: fix 'passing zero to ERR_PTR()' warning

Browse source

commit 934ffce134 upstream.

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: d809ec8955 ("xfrm: do not assume that template resolving always returns xfrms")
