After commit 26e495f34107 ("iommu/amd: Restore IRTE.RemapEn bit after
programming IRTE"), smatch warns:
drivers/iommu/amd/iommu.c:3870 amd_iommu_deactivate_guest_mode()
warn: variable dereferenced before check 'entry' (see line 3867)
Fix this by moving the @valid assignment to after @entry has been checked
for NULL.
