sys/linux: correct iommufd definitions
Some small mistakes have crept into here and the definitions are not
working quite right
The kernel changed the layout of the mock_domain test command to have
three handles and moved the device_handl to the end. A new handle - the
"selftest_device" was returned instead.
check_map/check_refs takes in a hwpt_handle not an fd_access
domain_replace takes in the selftest_device_handle and an ioas/pt
access_replace_ioas uses the ioas_handle not a naked int32.
