After a brief conversation with Sheikh Omar Al-Hamdoon, I have learned that there are some characteristics in Arabic language that can be shared between the Creator and the creation. Maulana is one of them amongst others. This one means associate, companion, etc.
Last week one of the things mentioned in the juma Khutba was "Protect Allah and Allah will protect you". At one place Allah SWT says "Give Allah Victory and Allah will give you Victory, this one means give victory to Allah's cause."
In a nutshell you can call someone "Maulana". Hope this clarifies the situation.
