wifi: rtl8xxxu: Fix skb misuse in TX queue selection

[ Upstream commit edd5747aa12ed61a5ecbfa58d3908623fddbf1e8 ]

rtl8xxxu_queue_select() selects the wrong TX queues because it's
reading memory from the wrong address. It expects to find ieee80211_hdr
at skb->data, but that's not the case after skb_push(). Move the call
to rtl8xxxu_queue_select() before the call to skb_push().
