Subject: net: remove the unnecessary strict_start_type in some policies
Patch-mainline: v5.5-rc1
Git-commit: f3bed7f8f93d60df11f94be14542682c905b5c3e
References: bsc#1154353
ct_policy and mpls_policy are parsed with nla_parse_nested(), which
does NL_VALIDATE_STRICT validation, strict_start_type is not needed
to set as it is actually trying to make some attributes parsed with
NL_VALIDATE_STRICT.
This patch is to remove it, and do the same on rtm_nh_policy which
is parsed by nlmsg_parse().
