Yanfei Xu 426bd74187 iommu/vt-d: Fix to flush cache of PASID directory table ...

[ Upstream commit 8a3b8e63f8 ]

Even the PCI devices don't support pasid capability, PASID table is
mandatory for a PCI device in scalable mode. However flushing cache
of pasid directory table for these devices are not taken after pasid
table is allocated as the "size" of table is zero. Fix it by
calculating the size by page order.

Found this when reading the code, no real problem encountered for now.
