iommu/amd/pgtbl_v2: Take protection domain lock before invalidating TLB

Commit c7fc12354be0 ("iommu/amd/pgtbl_v2: Invalidate updated page ranges
only") missed to take domain lock before calling
amd_iommu_domain_flush_pages(). Fix this by taking protection domain
lock before calling TLB invalidation function.
