net: use hlist_del_rcu() in dev_change_name()
[ Upstream commit 372b2312010bece1e36f577d6c99a6193ec54cbd ]
Using plain hlist_del() in dev_change_name() is wrong since a
concurrent reader can crash trying to dereference LIST_POISON1.
Bug introduced in commit 72c9528bab94 (net: Introduce
dev_get_by_name_rcu())
