====================
sctp: remove typedefs from structures part 4

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. This patchset is the
part 4 to remove it for another 14 basic structures from linux/sctp.h.
After this patchset, all typedefs are cleaned in linux/sctp.h.

Just as the part 1-3, No any code's logic would be changed in these patches,
only cleaning up.
