hsr: hold rcu and dev lock for hsr_get_port_ndev
[ Upstream commit 847748fc66d08a89135a74e29362a66ba4e3ab15 ]
hsr_get_port_ndev calls hsr_for_each_port, which need to hold rcu lock.
On the other hand, before return the port device, we need to hold the
device reference to avoid UaF in the caller function.
