benchdnn matmul with --wtag=acbd correctness test failure on CPU

[shu1chen]

Summary

When working on #2175, it's found that there is also a bug on x86_64. After the commit 3877097 on main branch, benchdnn correctness check fails after adding --wtag=acbd. It's good on the previous commit 6bfb6a8.

Version

onednn_verbose,v1,info,oneDNN v3.7.0 (commit 3877097)
onednn_verbose,v1,info,cpu,runtime:OpenMP,nthr:64
onednn_verbose,v1,info,cpu,isa:Intel AVX-512 with float16, Intel DL Boost and bfloat16 support and Intel AMX with bfloat16 and 8-bit integer support

Environment

• CPU: Intel (R) Xeon (R) CPU Max 9462
• OS version: Ubuntu 22.04
• Compiler version: gcc 11.4.0

Steps to reproduce

$ ./tests/benchdnn/benchdnn --engine=cpu --matmul --wtag=acbd --dtag=abcd 1x1x2x3:3x1x3x3

Expected behavior

Test pass. It's better to add a test for this use case.
