Don't throw an IOException if IBBStream got closed by the remote

Browse source 
Smack should not throw an IOException in case a stream got closed by
the remote peer and the user is trying to read() from the stream. This
commit fixes that, by making Smack return '-1' if the stream got
closed by the remote. An IOException will only be thrown if the user
tries to read from a stream that got already closed by *himself*.
