iommu/amd: Add missed 'tag' to error msg in iommu_print_event 

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/iommu/amd_iommu.c: In function 'iommu_print_event':
drivers/iommu/amd_iommu.c:550:33: warning:
 variable 'tag' set but not used [-Wunused-but-set-variable]

It was introduced in
  e7f63ffc1b ("iommu/amd: Update logging information for new event type")

seems just missed in the error message, add it as suggested by Joerg.
