iommu/arm-smmu-v3: Fix ECMDQs is not initialized correctly

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6WAZX



--------------------------------

When the number of cores is greater than the number of ECMDQs, the number
of ECMDQs occupied by each NUMA node is less than the number of cores of
the node. Therefore, the first smmu->nr_ecmdq cores do not cover all
ECMDQs.

For example:
 ---------------------------------------
|       Node0       |       Node1       |
|---------------------------------------|
|   0   1   2   3   |   4   5   6   7   |  CPU ID
|---------------------------------------|
|      0      1     |      2      3     |  ECMDQ ID
 ---------------------------------------
