Should having a prostate infection stop me from going ahead with a total hip replacement surgery?

Yes: Before any implant surgery, all evidence of infection should be cleared. A mild prostatitis without fevers or bacteria in the urine should clear with antibiotics and not delay surgery. A raging infection with fevers, bacteria in the urine and blood must be treated with major antibiotics to prevent seeding of the new joint.

Yes: Before elective surgery like knee replacement, all infections should be treated to prevent infection of the new implant.

Maybe: If the infection has been treated with antibiotics and is resolving you are probably okay. If not, the surgery should be postponed until the condition has been treated. More importantly, you should be evaluated for the cause of the infection and treated appropriately by a urologist.
