Bug Description

THD pointer for TOI BF aborts is not propagated to wsrep_innobase_kill_one_trx() in 5.6 branch. The reason is that TOI thd does not have trx registered in InnoDB at the moment the BF abort happens and wsrep_innobase_kill_one_trx() was simplified at some point to take only trx pointers as input.

This causes server freezes with mixed DML/DDL load.
