iommu/vt-d: Fix compile warning from intel-svm.h 

commit e7598fac32 upstream.

The intel_svm_is_pasid_valid() needs to be marked inline, otherwise it
causes the compile warning below:

  CC [M]  drivers/dma/idxd/cdev.o
In file included from drivers/dma/idxd/cdev.c:9:0:

 static int intel_svm_is_pasid_valid(struct device *dev, int pasid)
