common/mlx5: update doorbell mapping parameter name
The "tx_db_nc" devarg forces doorbell register mapping to non-cached region eliminating the extra write memory barrier. This argument was used in creating the UAR for Tx and thus affected its performance.
Recently [1] its use has been extended to all UAR creation in all mlx5 drivers, and now its name is no longer so accurate.
This patch changes its name to "sq_db_nc" to suit any send queue that uses it. The old name will still work for backward compatibility.
