s390/qeth: don't reset default_out_queue
[ Upstream commit240c194849
] When an OSA device in prio-queue setup is reduced to 1 TX queue due to HW restrictions, we reset its the default_out_queue to 0. In the old code this was needed so that qeth_get_priority_queue() gets the queue selection right. But with proper multiqueue support we already reduced dev->real_num_tx_queues to 1, and so the stack puts all traffic on txq 0 without even calling .ndo_select_queue. Thus we can preserve the user's configuration, and apply it if the OSA device later re-gains support for multiple TX queues. Fixes:73dc2daf11
