[dpdk-dev] [PATCH v2] examples/ioat: fix stats print

Currently some of the status string at the top of the stats output is being
cut off. To fix this, the status string array size has been increased.
In addition to this, the "\n" has been moved to the printf, rather than
having it in the last string, in case of future formatting issues due to
truncation.

Bugzilla ID: 536
Fixes: 632bcd9b5d4f ("examples/ioat: print statistics")

v2:
  - Increased string array by larger value - ie. up to 255.
  - Moved the "\n" to avoid future formatting issues from truncation.
