net: introduce netif_addr_lock_nested() and call if when appropriate
dev_uc_sync() and dev_mc_sync() are acquiring netif_addr_lock for destination device of synchronization. Since netif_addr_lock is already held at the time for source device, this triggers lockdep deadlock warning. There's no way this deadlock can happen so use spin_lock_nested() to silence the warning.
