tests/qtest: add a test case for pvpanic-pci
Add a test case for pvpanic-pci device. The scenario is the same as pvpanic ISA device, but is using the PCI bus. Signed-off-by: Mihai Carabas <mihai.carabas@oracle.com> Acked-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Mihai Carabas <mihai.carabas@oracle.com> [PMM: added code to free dev and pcibus, which the oss-fuzz build otherwise complains about as a leak] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
