[dpdk-dev] [PATCH] doc: fix code-block syntax

[Thomas Monjalon]

Some blocks are not visible with some Sphinx versions because
they are using the wrong keyword for code.

Tested with Sphinx v1.1.3.

Fixes: 1733be6d3147 ("doc: new eal multi-pthread feature")
Fixes: ccefe752cab0 ("doc: add jobstats sample guide")
