BUG#26976 - Missing table in merge not noted in related error msg +

            SHOW CREATE TABLE fails

Underlying table names, that merge engine fails to open were not
reported.

With this fix CHECK TABLE issued against merge table reports all
underlying table names that it fails to open. Other statements
are unaffected, that is underlying table names are not included
into error message.

This fix doesn't solve SHOW CREATE TABLE issue.
