Subject: [PATCH] net: Fix incorrect comment in netif_tx_stop_queue()

netif_stop_queue() can be called before register_netdev() because now
TX queues are allocated inside alloc_netdev_mqs().

(since ed9af2e839c06c18f721da2c768fbb444c4a10e5 commit)

Found by Linux Driver Verification project (linuxtesting.org).
