iommu: Pass domain to remove_dev_pasid() op
Existing remove_dev_pasid() callbacks of the underlying iommu drivers
get the attached domain from the group->pasid_array. However, the domain
stored in group->pasid_array is not always correct in all scenarios.
A wrong domain may result in failure in remove_dev_pasid() callback.
To avoid such problems, it is more reliable to pass the domain to the
remove_dev_pasid() op.
