hsr: use rtnl lock when iterating over ports

hsr_for_each_port is called in many places without holding the RCU read
lock, this may trigger warnings on debug kernels. Most of the callers
are actually hold rtnl lock. So add a new helper hsr_for_each_port_rtnl
to allow callers in suitable contexts to iterate ports safely without
explicit RCU locking.

This patch only fixed the callers that is hold rtnl lock. Other caller
issues will be fixed in later patches.

Fixes: c5a759117210 ("net/hsr: Use list_head (and rcu) instead of array for slave devices.")
