panic: assertion: error == 0 in hammer_start_transaction

[Matthew Dillon]

:Well it would be lovely if it wouldn't panic, but at least I have a faint idea
:what caused it and will be more careful in the future.

    Various error paths would have to be added to the transaction API
    to allow it to return an error and abort the sequence, instead
    of panicing there.  I'd rather not mess with it now but I guess we
    will want to deal with it at some point in the futue.
