udev: allow onboard index up to 65535
The maximum allowed value of the sysfs device index entry was limited to
16383 (2^14-1) to avoid the generation of unreasonable onboard interface
names.
For s390 the index can assume a value of up to 65535 (2^16-1) which is
now allowed depending on the new naming flag NAMING_16BIT_INDEX.
Larger index values are considered unreasonable and remain to be
ignored.
