net/mlx5e: Fix SQ wake logic in ptp napi_poll context

Browse source

commit 7aa5038019 upstream.

Check in the mlx5e_ptp_poll_ts_cq context if the ptp tx sq should be woken
up. Before change, the ptp tx sq may never wake up if the ptp tx ts skb
fifo is full when mlx5e_poll_tx_cq checks if the queue should be woken up.
