[Qemu-devel] [PULL 10/14] tests: qpci_unplug_acpi_device_test() should not rely on global_qtest

[Thomas Huth <thuth@redhat.com>]

libqos functions should not use functions that require global_qtest to
be set, since such library functions could also be used by tests that
deal with multiple test states. Add a parameter to this function to
explicitly specify the test state.
