====================
sctp: fix the issue that may copy duplicate addrs into assoc's bind address list

Patch 1/2 is to fix some indent level.

Given that we have kernels out there with this issue, patch 2/2 also
fix sctp_raw_to_bind_addrs.

v1 -> v2:
  Explain why we didn't filter the duplicate addresses when global
  address list gets updated in patch 2/2 changelog.
====================
