There are some bad indents of functions' defination in sm_make_chunk.c.
They have been there since beginning, it was probably caused by that
the typedef sctp_chunk_t was replaced with struct sctp_chunk.

So it's the best time to fix them in this patchset, it's also to fix
some bad indents in other functions' defination in sm_make_chunk.c.
