Merge branch 'sctp-align'

Marcelo Ricardo Leitner says:

====================
Rename WORD_TRUNC/ROUND macros and use them

This patchset aims to rename these macros to a non-confusing name, as
reported by David Laight and David Miller, and to update all remaining
places to make use of it, which was 1 last remaining spot.

v3:
- Name it SCTP_PAD4 instead of SCTP_ALIGN4, as suggested by David Laight
v2:
- fixed 2nd patch summary

Details on the specific changelogs.
====================
