Cleanup sctp_syscalls.c

[tuexen]

Summary

The original pattern of an SCTP syscall was

int syscall_name (td, uap)
{
#if (defined(INET) || defined(INET6)) && defined(SCTP)
  body
  return (error);
#else
  return (EOPNOTSUPP);
#endif
}

This was changed in r 363079

int syscall_name (td, uap)
{
#if defined(INET) || defined(INET6)
  body
  return (error);
#endif
}

This does not work when neither INET nor INET6 is defined, since the function is expected to return an int. I think this file is not intended to be compiled in this case, therefore I propose to remove the #ifdefs.

sys/conf/files contains

netinet/sctp_syscalls.c		optional inet sctp | inet6 sctp

and the SCTP module should also not be compiled on a kernel not supporting INET and not supporting INET6.

If the above analysis is not correct, one needs to re-add some #else clauses.

Do we still need opt_sctp.h?

Isn't it needed for the #ifdef SCTP I just re-added to register the syscalls?

Indeed, I was looking at the previous revision of this file.
