daemon: stream: don't update events if stream->closed

Calling virStreamFinish prematurely seems to trigger this code path
even after the stream is closed, which ends up hitting this error
message later:

error : virFDStreamUpdateCallback:127 : internal error: stream is not open

Skip this function if stream->closed, which is used in many other places
like read/write handlers
