Cong Wang 311633b604 hsr: switch ->dellink() to ->ndo_uninit()

Switching from ->priv_destructor to dellink() has an unexpected
consequence: existing RCU readers, that is, hsr_port_get_hsr()
callers, may still be able to read the port list.

Instead of checking the return value of each hsr_port_get_hsr(),
we can just move it to ->ndo_uninit() which is called after
device unregister and synchronize_net(), and we still have RTNL
lock there.

Fixes: b9a1e627405d ("hsr: implement dellink to clean up resources")
Fixes: edf070a0fb45 ("hsr: fix a NULL pointer deref in hsr_dev_xmit()")
