tests/qtest/iommu-smmuv3-test: Free QPCIDevice

The QPCIDevice we get via qpci_device_foreach() is allocated memory, and we need to g_free() it after use. This fixes asan leaks like this: Direct leak of 64 byte(s) in 1 object(s) allocated from: #0 0x622a5f16913d in calloc (/home/pm215/qemu/build/arm-clang/tests/qtest/iommu-smmuv3-test+0x1d413d) (BuildId: bc598be1f4ad6d1a9a600c55aeef36108bdb6a04) #1 0x73ee41c0f771 in g_malloc0 (/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x63771) (BuildId: 116e142b9b52c8a4dfd403e759e71ab8f95d8bb3) #2 0x622a5f1d4cec in qpci_device_find /home/pm215/qemu/build/arm-clang/../../tests/qtest/libqos/pci.c:82:11 #3 0x622a5f1d4cec in qpci_device_foreach /home/pm215/qemu/build/arm-clang/../../tests/qtest/libqos/pci.c:34:19 #4 0x622a5f23cc73 in setup_qtest_pci_device /home/pm215/qemu/build/arm-clang/../../tests/qtest/iommu-smmuv3-test.c:45:5 #5 0x622a5f23cc73 in run_smmuv3_translation /home/pm215/qemu/build/arm-clang/../../tests/qtest/iommu-smmuv3-test.c:74:11 Reviewed-by: Fabiano Rosas <farosas@suse.de> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 20260302092225.4088227-5-peter.maydell@linaro.org
