Subject: rtnetlink: do not set notification for tx_queue_len in do_setlink
Patch-mainline: v4.14-rc6
Git-commit: 2d7f669b42a97022c8c2b6cd86f3990be5fcd1bc
References: bsc#1109837

NETDEV_CHANGE_TX_QUEUE_LEN event process in rtnetlink_event would
send a notification for userspace and tx_queue_len's setting in
do_setlink would trigger NETDEV_CHANGE_TX_QUEUE_LEN.

So it shouldn't set DO_SETLINK_NOTIFY status for this change to
send a notification any more.
