iommu/amd: Fix I/O page table memory leak
The current logic updates the I/O page table mode for the domain before calling the logic to free memory used for the page table. This results in IOMMU page table memory leak, and can be observed when launching VM w/ pass-through devices.
Fix by freeing the memory used for page table before updating the mode.
