iommu: Make iommu_sva_domain_alloc() static

Browse Source 
iommu_sva_domain_alloc() is only called in iommu-sva.c, hence make it
static.

On the other hand, iommu_sva_domain_alloc() should not return NULL anymore
after commit <80af5a452024> ("iommu: Add ops->domain_alloc_sva()"), the
removal of inline code avoids potential confusion.

Fixes: 80af5a4520 ("iommu: Add ops->domain_alloc_sva()")
