Set invalid for questing, since it's planned kernel is 6.17 (hence will
incl. the fix once it's there).

Bug description:
s390/pci: Fix zpci_bus_is_isolated_vf() for non-VFs
Commit:

-------------------------
For non-VFs, zpci_bus_is_isolated_vf() should return false
because they
aren't VFs. While zpci_iov_find_parent_pf() specifically checks
if
a function is a VF, it then simply returns that there is no
parent. The
simplistic check for a parent then leads to these functions
being
confused with isolated VFs and isolating them on their own
domain even
if sibling PFs should share the domain.
Fix this by explicitly checking if a function is not a VF. Note
also
that at this point the case where RIDs are ignored is already
handled
and in this case all PCI functions get isolated by being
detected in
zpci_bus_is_multifunction_root().
