This patchset fixes various leaks that show up if you run
migration-test under the clang leak-sanitizer. Since they're all
test code problems, this is 9.2 material. The one leak that was
really in the QEMU code I have sent a separate patch for:
https://patchew.org/QEMU/20240820144429.320176-1-peter.maydell@linaro.org/

You can repro these leaks by building a QEMU configured with
 '--cc=clang' '--cxx=clang++' '--enable-debug' '--target-list=x86_64-softmmu' '--enable-sanitizers'
and then running the test like:
(cd build/asan && \
 ASAN_OPTIONS="fast_unwind_on_malloc=0" \
 QTEST_QEMU_BINARY=./qemu-system-x86_64 ./tests/qtest/migration-test --tap -k )

thanks
