Remove dead code for "InnoDB table(space) monitor"

Starting with MySQL 5.7 (or MariaDB 10.2.2) InnoDB no longer contains
the "table monitor" or "tablespace monitor". The conditions on
srv_print_innodb_tablespace_monitor, srv_print_innodb_table_monitor
never hold. So, the code was dead.

Also, remove a bogus reference to dict_print(), which used to implement
the InnoDB table monitor.
