Fix for bug#37527: mysqlcheck fails to report entire database

Browse Source 
when InnoDB frm file corruption

Problem: mysqlcheck runs 'SHOW FULL TABLE' queries to get table lists.
The query may fail for some reasons (e.g. null .frm file) then
mysqlcheck doesn't process the database tables.

Fix: try to run 'SHOW TABLES' if 'SHOW FULL TABLES' failed.


client/mysqlcheck.c:
  Fix for bug#37527: mysqlcheck fails to report entire database
