Since we have already fixed qpci to avoid global_qtest, we can now simplify by not using global_qtest anywhere in ivshmem-test. 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).
