In general I like those changes, just returning a pointer is
definitely not enough.

However -- is returning NT_STATUS_OK really the right thing for the
client_init function when it did not work? Shouldn't we lift the error
handling a bit up? NT_STATUS_OK tells the caller everything was fine,
and I would expect crashes later on trying to dereference the
messaging context pointer.
