assert failure in journal vdev during replication I/O load with truncation and snapshot

[yamingk]

So far this is seen on testing with file once (not able to reproduce often).

test_raft_repl_dev: /tmp/source/yk_hs/src/lib/device/journal_vdev.cpp:642: std::tuple<std::shared_ptr<homestore::Chunk>, unsigned int, long int> homestore::JournalVirtualDev::Descriptor::offset_to_chunk(off_t, bool) const: Assertion `0' failed.
