[patch] sctp: fix test for end of loop

[Dan Carpenter <error27@gmail.com>]

"new_addr" is the list cursor here and it's always non-NULL.

We're trying to test if we exited because the loop ended or we hit the
break statement.  Really testing !found is enough so long as 
"new_asoc->peer.transport_addr_list" is not empty and I believe it never
is empty at this point.  So this is never really a bug with the current
code.
