[PATCH 5.2 113/135] sctp: fix memleak in sctp_send_reset_streams

[Sasha Levin]

From: zhengbin <zhengbi...@huawei.com>

[ Upstream commit 6d5afe20397b478192ed8c38ec0ee10fa3aec649 ]

If the stream outq is not empty, need to kfree nstr_list.

Fixes: d570a59c5b5f ("sctp: only allow the out stream reset when the stream 
outq is empty")
