Cleaned up some misleading comments

1) global_acc_reg_num_table and global_acc_reg_str_table are used in the login server only and their configuration and access is not shared with any other component.
2) The character server does not check for global_acc_reg_str_table and global_acc_reg_str_table, but for acc_reg_str_table and acc_reg_str_table.
