------------------------------------------------------
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Subject: test_hexdump: test all possible group sizes for overflow

Currently only one combination is tested for overflow, i.e. rowsize = 16,
groupsize = 1, len = 1.  Do various test to go all possible branches.
