Bug #31868 mysql_server_init crash when language path is not correctly set.

Browse Source 
When mysql_server_init() interrupts on some error (wrong errmsg file
for example) in the middle of it's execution, it doesn't call
execute_ddl_log_recovery() so LOCK_gdl mutex isn't init-ed.
In this case we shouldn't execute release_ddl_log during cleanup
as it uses that mutex inside.
