====================
sctp: remove typedefs from structures part 1

As we know, typedef is suggested not to use in kernel, even checkpatch.pl
also gives warnings about it. Now sctp is using it for many structures.

All this kind of typedef's using should be removed. As the 1st part, this
patchset is to remove it for 11 basic structures in linux/sctp.h. It is
also to fix some indents.

No any code's logic is changed in these patches, only cleaning up.
