iommu/amd: Fix argument order in amd_iommu_dev_flush_pasid_all()

Browse source

An incorrect argument order calling amd_iommu_dev_flush_pasid_pages()
causes improper flushing of the IOMMU, leaving the old value of GCR3 from
a previous process attached to the same PASID.

The function has the signature:

void amd_iommu_dev_flush_pasid_pages(struct iommu_dev_data *dev_data,
				     ioasid_t pasid, u64 address, size_t size)

Correct the argument order.
