  The prepend function did not handle non-pkthdr's correctly.
  It always called MH_ALIGN for small lengths being
  prepended (less than MHLEN). This meant that if you did
  a prepend on a non M_PKTHDR the system would panic with
  the KASSERT in MH_ALIGN. Instead we are not aware of
  this and do a MH_ALIGN or M_ALIGN as appropriate.
