test_graph_unit_dnnl_convolution_cpu fails on AArch64 CI after recent quantization refactor

[michalowski-arm]

Summary

After a recent quantization refactor (#2270) we see a failure in Nightly AArch64 pipeline (https://github.com/oneapi-src/oneDNN/actions/runs/13066726551/job/36460347340). Upon bisecting, the first bad commit appears to be af1410c.

Version

ACL version v24.11.1

Environment

OneDNN GitHub CI for AArch64, c7g AWS instance

Steps to reproduce

ctest -R "test_graph_unit_dnnl_convolution_cpu" --rerun-failed --output-on-failure

Observed behavior

[ RUN ] test_convolution_execute.ConvBiasAddEltwise
/opt/actions-runner/_work/oneDNN/oneDNN/oneDNN/tests/gtests/graph/unit/backend/dnnl/test_convolution.cpp:2557: Failure
Expected equality of these values:
dst[i]
Which is: -0.072591752
param.ref_dst[I]
Which is: -0.072591871
[ FAILED ] test_convolution_execute.ConvBiasAddEltwise (23 ms)

Expected behavior

Test OK

@dzarukin, this appears to be your change

Hi @michalowski-arm. Though it may be triggered by my changes, the problem seems to be in the way the test compares results. I'll check how to update it.

@dzarukin this seems to be affecting our nightly and precommit pipelines as well: https://github.com/oneapi-src/oneDNN/actions/runs/13128702961

Please remember to revert #2599 in the same patch as the fix for this issue to show the issue is fixed. Thanks.
