MDEV-13797 InnoDB may hang if shutdown is initiated soon after startup while rolling back recovered incomplete transactions

Browse Source 
trx_rollback_resurrected(): If shutdown was initiated, fake all
remaining active transactions to XA PREPARE state, so that shutdown
can proceed. Also, make the parameter "all" an output that will be
assigned to FALSE in this case.

trx_rollback_or_clean_recovered(): Remove the shutdown check
(it was moved to trx_rollback_resurrected()).

trx_undo_free_prepared(): Relax assertions.
