[dpdk-stable] [PATCH 05/14] examples/ioat: fix stats print

[谢华伟(此时此刻）]

From: Kevin Laatz <kevin.laatz at intel.com>

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")
Cc: stable at dpdk.org
