[CI] set DG_NVCC_OVERRIDE_CPP_STANDARD in test_quantized_linear

[EmmonsCurse]

Motivation

In some environments, running test_quantized_linear.py fails due to a deep_gemm JIT compilation error where nvcc rejects the -std=c++20 flag.
To ensure consistency between runtime and test environments, we set DG_NVCC_OVERRIDE_CPP_STANDARD=17 inside the test script to avoid build failures when the environment variable is not explicitly defined.

Modifications

Added the following line in tests/layers/test_quantized_linear.py:

os.environ.setdefault("DG_NVCC_OVERRIDE_CPP_STANDARD", "17")

Usage or Command

python -m pytest -sv tests/layers/test_quantized_linear.py
