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.
