This extends IOMMU_TEST_OP_MOCK_DOMAIN to accept a pasid from caller. Hence it is able to cover the iommufd_device_bind_pasid() for SIOV virtual devices. pasid #0 is selected to mark the physical devices, non-zero pasid values would be considered as SIOV virtual device bind. Will add SIOV test cases later.
