s390x/pci: reflect proper maxstbl for groups of interpreted devices

Git-commit: 9ee8f7e46a References: jsc#PED-1716 The maximum supported store block length might be different depending on whether the instruction is interpretively executed (firmware-reported maximum) or handled via userspace intercept (host kernel API maximum). Choose the best available value during group creation.
