Fix a few problems that Bruce noticed about a month ago, and fix oup one
other problem.

- Hold onto splsoftcam() in the peripheral driver open routines until we
  have locked the periph.  This eliminates a race condition.

- Disallow opening the pass driver when securelevel > 1.

- If a user tries to open the pass driver with O_NONBLOCK set, return
  EINVAL instead of ENODEV.  (noticed by gibbs)
