Marc-André Lureau 9cbc36497c migration: fix cleanup_bh leak on resume 
Since commit 8c6b0356b5 ("util/async:
make bh_aio_poll() O(1)"), migration-test reveals a leak:

QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64
tests/qtest/migration-test  -p /x86_64/migration/postcopy/recovery
tests/qtest/libqtest.c:140: kill_qemu() tried to terminate QEMU
process but encountered exit status 1 (expected 0)
