  Log:
  Change M_WAITOK argument to sodupsockaddr() to M_NOWAIT.  When the call
  to dup_sockaddr() was renamed to sodupsockaddr(), the argument was
  changed from '1' to 'M_WAITOK', which changed the semantics.  This
  resulted in a WITNESS warning about a potential sleep while holding the
  NFS server mutex.  Now this will no longer happen, restoring a possible
  bug present in the original code (setting RC_NAM even though the malloc
  to copy the addres may fail).  bde observes that the flag names here
  should probably not be the same as the malloc flags for name space
  reasons.
