[Qemu-ppc] [PATCH v7 11/38] libqos: Use explicit QTestState for pci operations

[Eric Blake]

Now that the QPCIBus tracks QTestState, use that state instead
of an implicit reliance on global_qtest.

Pass an explicit QTestState to the remaining few functions in
the same file that don't have direct access to QPCIBus, and
update all callers.

Signed-off-by: Eric Blake <address@hidden>

v7: more sites with explicit state, drop R-b
