spike cound easily overflow queue demanding tunnel disconnection due
to possible state inconsistency.

- Use callout_pending() instead of our own flags.
- Remove home-grown protection of node, which has a scheduled
  callout().
- Remove spl(9) calls.

ddb7229415 Correct L2TP header offset handling: 
- according to RFC2661 an offset size of 0 is allowed.
- when skipping offset padding do not forget to also skip
  the 2 octets of the offset size field.

Should make no binary difference.

44956c9863 Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.

86fea6be59 o Untangle the confusion with the malloc flags {M_WAITOK, M_NOWAIT} and 
the mbuf allocator flags {M_TRYWAIT, M_DONTWAIT}.
o Fix a bpf_compat issue where malloc() was defined to just call
  bpf_alloc() and pass the 'canwait' flag(s) along.  It's been changed
  to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT
  flag (and only one of those two).
