Prevent the VF from attempting to update the GuC reset policy when
changing the wedged mode, as this operation is not supported on VFs.
Additionally, validate the wedged_mode module parameter input, update
the internal wedged.mode state only on success, and allow setting
wedged_mode=2 only in debug builds if running as PF.

v3: Rename xe_device_wedged_mode_validate to
