cxgb3: Fix crash caused by stashing wrong netdev_queue
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().
