Bug#23831  deadlock not noticed

RBR bug in that when replicated msta (multi-statement-trans-action) deadlocks
with a local at write row event or gets timed-out, the event handler did not return
the correct error code.
Wrong error code stops slave sql thread instead of to proceed with
rollback and replay.

The correct code is typed in error log and stored for error handling rotine
to conduct rollback and replay of the transaction. The handling for the rbr
remains the same as for the sbr events.
Particularly, timed-out transaction still is rolled back - look at the related bugs.
