sctp: dubious bitfields in sctp_transport

Sparse complains because these one-bit bitfields are signed.
  include/net/sctp/structs.h:879:24: error: dubious one-bit signed bitfield
  include/net/sctp/structs.h:889:31: error: dubious one-bit signed bitfield
  include/net/sctp/structs.h:895:26: error: dubious one-bit signed bitfield
  include/net/sctp/structs.h:898:31: error: dubious one-bit signed bitfield
  include/net/sctp/structs.h:901:27: error: dubious one-bit signed bitfield

It doesn't cause a problem in the current code, but it would be better
to clean it up.  This was introduced by c0058a35aacc7: "sctp: Save some
room in the sctp_transport by using bitfields".
