Subject: [V2 net 06/16] net/mlx5: ASO, Create the ASO SQ with the correct timestamp format

From: Saeed Mahameed <saeedm@...dia.com>

mlx5 SQs must select the timestamp format explicitly according to the
active clock mode, select the current active timestamp mode so ASO SQ create
will succeed.

This fixes the following error prints when trying to create ipsec ASO SQ
while the timestamp format is real time mode.

mlx5_cmd_out_err:778:(pid 34874): CREATE_SQ(0x904) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xd61c0b), err(-22)
mlx5_aso_create_sq:285:(pid 34874): Failed to open aso wq sq, err=-22
mlx5e_ipsec_init:436:(pid 34874): IPSec initialization failed, -22

Fixes: cdd04f4d4d71 ("net/mlx5: Add support to create SQ and CQ for ASO")
