The value of the DCGM_FI_DEV_XID_ERRORS field is always printed twice

[nvvfedorov]

The DCGM_FI_DEV_XID_ERRORS field value is always printed twice.

Steps to reproduce:

1. Run DCGM-Exporter.
2. Collect and check metrics output.

curl localhost:9400/metrics

Expected:

# HELP DCGM_FI_DEV_XID_ERRORS Value of the last XID error encountered.
# TYPE DCGM_FI_DEV_XID_ERRORS gauge
DCGM_FI_DEV_XID_ERRORS{gpu="0",UUID="GPU-aee734e0-1a3d-2715-f7e1-4d9d89dc56f2",device="nvidia0",modelName="NVIDIA A100 80GB PCIe",GPU_I_PROFILE="2g.20gb",GPU_I_ID="3",Hostname="4u4g-0018",DCGM_FI_DRIVER_VERSION="555.23"} 0

Actual:

# HELP DCGM_FI_DEV_XID_ERRORS Value of the last XID error encountered.
# TYPE DCGM_FI_DEV_XID_ERRORS gauge
DCGM_FI_DEV_XID_ERRORS{gpu="0",UUID="GPU-aee734e0-1a3d-2715-f7e1-4d9d89dc56f2",device="nvidia0",modelName="NVIDIA A100 80GB PCIe",GPU_I_PROFILE="2g.20gb",GPU_I_ID="3",Hostname="4u4g-0018",DCGM_FI_DRIVER_VERSION="555.23"} 0
