Further locking improvements for vr(4):
 - Add *_locked() entry points as needed to avoid unnecessary lock thrashing.
 - Use these entry points wisely.
 - Only acquire the lock once when servicing an interrupt.
 - Check 'suspended' on interrupt to avoid racing detach.
 - Correct a mis-spelled comment.
 - Don't take the lock in vr_reset() to avoid lock thrashing in attach.
  - Comment this.
