GFX 12.1.0 queues are managed by MES, not by the HWS runlist, so the
127 queue limit does not apply.
The topology advertises 32 CP queues plus 16 SDMA engines with 6 queues
each, so creating every queue needs 128 and the last one fails with
-ENOSPC:
[ RUN ] KFDQMTest.AllQueues
KFDQMTest.cpp:365: Failure
Value of: (sdmaQueues[j].Create(gpuNode))
Actual: 1
Expected: HSAKMT_STATUS_SUCCESS
[ FAILED ] KFDQMTest.AllQueues
