net/mlx5: Set QP timestamp mode to default
QPs which don't care from timestamp mode, should set the ts_format to default, otherwise the QP creation could be failed if the timestamp mode is not supported. Fixes: 2fe8d4b87802 ("RDMA/mlx5: Fail QP creation if the device can not support the CQE TS") Signed-off-by: Maor Gottlieb <maorg@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
