hv_netvsc: Simplify the limit check in netvsc_set_channels()
Because of the following code, net->num_tx_queues equals to VRSS_CHANNEL_MAX, and max_chn is less than or equals to VRSS_CHANNEL_MAX. netvsc_drv.c: alloc_etherdev_mq(sizeof(struct net_device_context), VRSS_CHANNEL_MAX); rndis_filter.c: net_device->max_chn = min_t(u32, VRSS_CHANNEL_MAX, num_possible_rss_qs); So this patch removes the unnecessary limit check before comparing with "max_chn".
