net: macvlan: Use built-in RCU list checking
hlist_for_each_entry_rcu() has built-in RCU and lock checking.
Pass cond argument to hlist_for_each_entry_rcu() to silence false
lockdep warning when CONFIG_PROVE_RCU_LIST is enabled.
Execute as follow:
ip link add link eth0 type macvlan mode source macaddr add <MAC-ADDR>
The rtnl_lock is held when macvlan_hash_lookup_source() or
macvlan_fill_info_macaddr() are called in the non-RCU read side section.
So, pass lockdep_rtnl_is_held() to silence false lockdep warning.
