tetheroffload VTS: fix stopOffload test conditions
The tetheroffload HAL is somewhat...and over- and under-specified.
A not unreasonable interpretation is that stopOffload() doesn't have
return success unless offload was actually started (via a call to
setUpstreamParameters()), and that after initOffload() and before
setUpstreamParameters() not actual "offload" has been engaged.
Precision in this matter is not required for the test case:
OffloadControlHidlTestBase.AdditionalInitsWithoutStopReturnFalse
But for the test case:
OffloadControlHidlTestBase.AdditionalStopsWithInitReturnFalse
we want to ensure the "matching" stopOffload call succeeds. For this
test we add in a call to setUpstreamParameters() for good measure.
Test: as follows
prompt$ make vts -j30 BUILD_GOOGLE_VTS=true && \
vts-tradefed run commandAndExit vts \
--skip-all-system-status-check \
--primary-abi-only \
--skip-preconditions \
--module VtsHalTetherOffloadControlV1_0Target \
