Start working through inpcb locking for ip_ctloutput() by cleaning up
modifications to the inpcb IP options mbuf:

- Lock the inpcb before passing it into ip_pcbopts() in order to prevent
  simulatenous reads and read-modify-writes that could result in races.
- Pass the inpcb reference into ip_pcbopts() instead of the option chain
  pointer in the inpcb.
- Assert the inpcb lock in ip_pcbots.
- Convert one or two uses of a pointer as a boolean or an integer
  comparison to a comparison with NULL for readability.
