[PATCH v2] doc: remove empty section from testpmd guide

[Thomas Monjalon <thomas@monjalon.net>]

When removing the documentation for the obsolete flow filtering,
the related section was kept almost empty.
It can be safely removed.

Fixes: 5007ac13189d ("ethdev: remove deprecated Flow Director configuration")
