sctp: remove the unnecessary sinfo_stream check in sctp_prsctp_prune_unsent 

Since commit 5bbbbe32a4 ("sctp: introduce stream scheduler foundations"),
sctp_stream_outq_migrate() has been called in sctp_stream_init/update to
removes those chunks to streams higher than the new max. There is no longer
need to do such check in sctp_prsctp_prune_unsent().
