Alexey Kodanev 00ec3b0ca3 sctp: fix dst refcnt leak in sctp_v6_get_dst()
[ Upstream commit 957d761cf9 ]

When going through the bind address list in sctp_v6_get_dst() and
the previously found address is better ('matchlen > bmatchlen'),
the code continues to the next iteration without releasing currently
held destination.

Fix it by releasing 'bdst' before continue to the next iteration, and
instead of introducing one more '!IS_ERR(bdst)' check for dst_release(),
move the already existed one right after ip6_dst_lookup_flow(), i.e. we
shouldn't proceed further if we get an error for the route lookup.

Fixes: dbc2b5e9a0 ("sctp: fix src address selection if using secondary addresses for ipv6")
