commit b4cc2c96aea71a95daf0f7e4cece045bfce9a6ad

    tests: Avoid free-ing a random FD in OwnedFd drop
    
    In the insert_bad_source test, we drop the FD "420", which doesn't exist.
    Previously the error was ignored, but in the latest nightly it now aborts the
    program. This commit fixes this by leaking the bad "OwnedFd" instead of leaving
    it to be dropped.
