dlls/ole32/bindctx.c: fix possible object reference count error

[Rolf Kalbermatter]

Changelog
  - dlls/ole32/bindctx.c
    Make sure the passed in object pointer is only addrefed on success

I may miss something here but believe that a function should only addref
a passed in object reference if it does use that object in some ways but
not if it fails on its supposed action somehow.
