Log message:
Use 64bit unsigned value for maximum stripe size test.
While STRIPE_SIZE_LIMIT * 2 is basically UINT_MAX, 32bit integer
value can already overflow durin arg size parsing.
(This really happens in test where --stripesize 4294967291 is used,
in s390x uint overflow and this test is ineffective.)
