net: dsa: remove lockdep class for DSA master address list
Since commit 2f1e8ea726e9 ("net: dsa: link interfaces with the DSA
master to get rid of lockdep warnings"), suggested by Cong Wang, the
DSA interfaces and their master have different dev->nested_level, which
makes netif_addr_lock() stop complaining about potentially recursive
locking on the same lock class.
So we no longer need DSA masters to have their own lockdep class.
