  Modified files:
    sys/pci              if_vr.c 
  Log:
  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.
