Description:
There is a missing return after line 16399 in DblqhMain.cpp.
This leads to a crash immediately after.

How to repeat:
Fix ndb_transaction_memory_shortage test case.
1) Remove ERROR_INSERTED_CLEAR(5031) in 2 places
2) Add && !ERROR_INSERTED(5031) in seize_op_rec in Dblqh
to ensure that we call oprec_pool.seize.

Suggested fix:
Add a return + other fixes

Documented fix as follows in the NDB 8.0.29 changelog:

    In DblqhMain.cpp, a missing return in the internal
    execSCAN_FRAGREQ() function led to an unplanned shutdown of the
    data node when inserting a nonfatal error.

Closed.
