As 'vnum' is controlled by user, so if user tries to allocate memory larger
than(>=) MAX_ORDER, then kcalloc() will fail, it creates a stack trace and
messes up dmesg with a warning.
Add __GFP_NOWARN in order to avoid too large allocation warning. This is
detected by static analysis using smatch.
Fixes: c3e2fe9222d4 ("scsi: scsi_debug: Implement VERIFY(10), add VERIFY(16)")
