Subject: [PATCH] netowkrd: initialize variables

Before this, in manager_rtnl_process_rule(), iif and oif are not
initialized. However, message may not contain FRA_IIFNAME or
FRA_IIFNAME. Thus, uninitialized values are set to RoutingPolicyRule
and causes segfault.
This makes iif and oif be initialized as NULL.

Fixes #7704.
