iommu/amd: Fix workqueue name

iommu/amd: Fix workqueue name

Workqueue name length is crossing WQ_NAME_LEN limit. Fix it by changing
name format. New format : "iopf_queue/amdvi-<iommu-devid>"

kernel warning:
  [   11.146912] workqueue: name exceeds WQ_NAME_LEN. Truncating to: iopf_queue/amdiommu-0xc002-iopf
