net/mlx5e: Use a barrier after updating txq2sq

Browse source

mlx5e_build_txq_maps updates txq2sq while TX queues are stopped. Add a
barrier to ensure that these changes are visible before the queues are
started and mlx5e_xmit reads from txq2sq.

This commit handles regular TX queues. Synchronization between HTB TX
queues and mlx5e_xmit is handled in the following commit.
