THAT FAILS FK CHECK IN FED TABLE

Description: A HANDLER within a stored procedure which
catches foreign key failures is currently not possible if
the table involved is using FEDERATED storage engine.

Analysis:- Remote server errors such as ER_NO_REFERENCED_ROW
and ER_NO_REFERENCED_ROW_2 are not handled inside
ha_federated::stash_remote_error() which in turn makes a
stored procedure impossible to define a HANDLER that will
catch a foreign key failure due to the error, "Cannot add or
update a child row: a foreign key constraint fails"

Fix: ER_NO_REFERENCED_ROW and ER_NO_REFERENCED_ROW_2 are
handled correctly in ha_federated::stash_remote_error`().
