[PATCH] netfilter: conntrack: Fix ifdef checks for CONFIG_NF_CONNTRACK_MARK

[joseph.j.conley@gmail.com]

From: Joe Conley <joe.conley@lairdtech.com>

Two missing ifdef checks for CONFIG_NF_CONNTRACK_MARK were causing
EOPNOTSUPP to be returned. Every single place that cda[CTA_MARK] or cda[CTA_MARK_MASK]
was checked was inside a #ifdef for CONFIG_NF_CONNTRACK_MARK except for these
two places. The reason for this change stems from this commit:
866476f323465a8afef10b14b48d5136bf5c51fe (netfilter: conntrack: Flush connections with a given mark)

This allows conntrack -L to be ran succesfully when CONFIG_NF_CONNTRACK_MARK
is not enabled.
