Fix messiah skill whe using VRPlus payday2 mod.

Fix for messiah skill in Payday2 VR

Full disclosure - I did encounter a hard crash (probably a deadlock) when activating messiah in VR while simultaneously being revived. Hard to say if it was related - occurred before I added the return instruction at the end of the messiah activation code. Perhaps that might fix the issue, or maybe it's just a terrible race condition.
