Subject: [ 08/72] sctp: dont break the loop while meeting the active_path so as to find the matched transport

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Xufeng Zhang <xufeng.zhang@...driver.com>

[ Upstream commit 2317f449af30073cfa6ec8352e4a65a89e357bdd ]

sctp_assoc_lookup_tsn() function searchs which transport a certain TSN
was sent on, if not found in the active_path transport, then go search
all the other transports in the peer's transport_addr_list, however, we
should continue to the next entry rather than break the loop when meet
the active_path transport.
