Fix broken imports on netperf2

Summary: The client/bin/autotest_utils.py rename required a fairly large
patch to fix out the tests due to the API breakage. This patch fixes a
broken import leftover from the process.

Visibility: Small (only users of the netperf2 test)

Impact: Small (only users of the netpef2 test, small fix)
