Subject: [PATCH 20/28] Fix --seq mode checksum with multiple stressors and
sanity checking
The sanity checking of bogo ops is using the same base offset of
the checksum pointer for each round of stressor being run. Fix this
by ensuring it is incremented per run so that the sanity checking
checksumming and bogo op counter is stashed in the correct slot.
