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)
