This issue was triggered with SCTP_PR_SCTP_PRIO in sctp,
and caused by not checking and fixing stream->out_curr
after removing a chunk from this stream.

Patch 1 removes an unnecessary check and makes the real
fix easier to add in Patch 2.

Xin Long (2):
  sctp: remove the unnecessary sinfo_stream check in
    sctp_prsctp_prune_unsent
  sctp: clear out_curr if all frag chunks of current msg are pruned
