commit 68c57bfd52836e31bff33e5e1fc64029749d2c35 upstream.
Symptom: Error message "Configuring the VNIC characteristics failed" in dmesg whenever an OSA interface on z15 is set online.
The VNIC characteristics get re-programmed when setting a L2 device online. This follows the selected 'wanted' characteristics - with the exception that the INVISIBLE characteristic unconditionally gets switched off.
For devices that don't support INVISIBLE (ie. OSA), the resulting IO failure raises a noisy error message ("Configuring the VNIC characteristics failed"). For IQD, INVISIBLE is off by default anyways.
So don't unnecessarily special-case the INVISIBLE characteristic, and thereby suppress the misleading error message on OSA devices.
