Eric Blake a189a9375b ahci-test: Drop dependence on global_qtest
Managing parallel connections to two different monitors via
the implicit global_qtest makes it hard to copy-and-paste code
to tests that are not aware of the implicit state; the
management of global_qtest is even harder to follow because
it was masked behind set_context().

Instead, explicitly pass QTestState* around (generally, by
reusing the member already present in ahci->parent QOSState),
and call explicit qtest_* functions on all places that
interact with a monitor.

We can assert that the conversion is correct by checking that
global_qtest remains NULL throughout the test (a later patch
that changes global_qtest to not be a public global variable
will drop the assertions).
