sctp: Fix oops when INIT-ACK indicates that peer doesn't support AUTH
If INIT-ACK is received with SupportedExtensions parameter which
indicates that the peer does not support AUTH, the packet will be
silently ignore, and sctp_process_init() do cleanup all of the
transports in the association.
When T1-Init timer is expires, OOPS happen while we try to choose
a different init transport.
The solution is to only clean up the non-active transports, i.e
the ones that the peer added. However, that introduces a problem
with sctp_connectx(), because we don't mark the proper state for
the transports provided by the user. So, we'll simply mark
user-provided transports as ACTIVE. That will allow INIT
retransmissions to work properly in the sctp_connectx() context
and prevent the crash.
