hsr: use hsr_for_each_port_rtnl in hsr_port_get_hsr
[ Upstream commit 393c841fe4333cdd856d0ca37b066d72746cfaa6 ]
hsr_port_get_hsr() iterates over ports using hsr_for_each_port(),
but many of its callers do not hold the required RCU lock.
Switch to hsr_for_each_port_rtnl(), since most callers already hold
the rtnl lock. After review, all callers are covered by either the rtnl
lock or the RCU lock, except hsr_dev_xmit(). Fix this by adding an
RCU read lock there.
Fixes: c5a759117210 ("net/hsr: Use list_head (and rcu) instead of array for slave devices.")
