Optional: It's probably reasonable to move this out of #ifdef block because it's required in both cases. (Note that netinet/sctp_pcb.h doesn't seem to need anything from sctp_crc32.h either, so that could be moved out too).

Is this order okay after moving these 2 include outside of #ifdef?

This is one of the call; so move it outside #ifdef.
