ipv6: add exception routes to GC list in rt6_insert_exception
Commit 5eb902b8e719 ("net/ipv6: Remove expired routes with a separated list
of routes.") introduced a separated list for managing route expiration via
the GC timer.
However, it missed adding exception routes (created by ip6_rt_update_pmtu()
and rt6_do_redirect()) to this GC list. As a result, these exceptions were
never considered for expiration and removal, leading to stale entries
persisting in the routing table.
This patch fixes the issue by calling fib6_add_gc_list() in
rt6_insert_exception(), ensuring that exception routes are properly tracked
and garbage collected when expired.
Fixes: 5eb902b8e719 ("net/ipv6: Remove expired routes with a separated list of routes.")
