jhb c08a62eaa2 - Add locking and mark MPSAFE. The driver had a mutex in the softc and 
even initialized it, but it never used it.
- Use callout_*() to manage the callout.
- Use m_devget() to copy data out of the rx buffers rather than doing it
  all by hand.
- Use m_getcl() to allocate mbuf clusters rather than doing it all by hand.
- Don't free the software descriptor for a rx ring entry if we can't
  allocate an mbuf cluster for it.  We left a dangling pointer and never
  reallocated the entry anyway.  OpenBSD's code (from which this was
  derived) has the same bug.
