Fix double close in RecordedTransaction fuzzer

BUG=271692937

Test: The issue is reproducible on devices with HWASan:

SANITIZE_TARGET=hwaddress make binder_recordedTransactionFileFuzz
$ cd ${ANDROID_PRODUCT_OUT}
$ adb root
$ adb sync data
$ adb shell /data/fuzz/$(get_build_var
TARGET_ARCH)/binder_recordedTransactionFileFuzz/binder_recordedTransactionFileFuzz

Without the fix, fdsan fails immediately. With the fix, the fuzzer runs
successfully.
