[PATCH] net/mlx5: set correct CPU socket ID for mlx5_rxq_ctrl

[Thinh Tran <thinhtr@linux.vnet.ibm.com>]

I hit a failure during ports drop queue RQ creation when my adapters
are on CPU socket ID 1 instead of socket ID 0:
....
EAL: Probe PCI driver: mlx5_pci (15b3:1019) device: 0020:01:00.0 (socket 1)
EAL: set_mempolicy failed: Invalid argument
mlx5_common: Failed to allocate memory for RQ.
mlx5_net: Port 0 drop queue RQ creation failed.
mlx5_net: Cannot create drop RX queue
mlx5_net: probe of PCI device 0020:01:00.0 aborted after encountering an error: Success
EAL: Probe PCI driver: mlx5_pci (15b3:1019) device: 0020:01:00.1 (socket 1)
EAL: set_mempolicy failed: Invalid argument
mlx5_common: Failed to allocate memory for RQ.
mlx5_net: Port 0 drop queue RQ creation failed.
mlx5_net: Cannot create drop RX queue
mlx5_net: probe of PCI device 0020:01:00.1 aborted after encountering an error: Success
TELEMETRY: No legacy callbacks, legacy socket not created
testpmd: No probed ethernet devices
...

The patch sets the correct CPU socket ID for the mlx5_rxq_ctrl before
calling the mlx5_rxq_create_devx_rq_resources() which eventually calls
mlx5_devx_rq_create() with correct CPU socket ID.
Result with this patch:
......
EAL: Probe PCI driver: mlx5_pci (15b3:1019) device: 0020:01:00.0 (socket 1)
EAL: Probe PCI driver: mlx5_pci (15b3:1019) device: 0020:01:00.1 (socket 1)
TELEMETRY: No legacy callbacks, legacy socket not created
Interactive-mode selected
......
Configuring Port 0 (socket 1)
Port 0: 0C:42:A1:ED:C1:20
Configuring Port 1 (socket 1)
Port 1: 0C:42:A1:ED:C1:21

Done
