>Description:

On executing vnconfig(8), kernel prints messages like
> vnd0: vnode disk driver
> vnd0 detached
even if no vnd(4) device is configured.

>How-To-Repeat:

# vnconfig -l
vnd0: vnode disk driver
vnd0: not in usevnd0 detached

vnd1: not in use
vnd2: not in use
vnd3: not in use
# vnconfig -l
vnd0: vnode disk driver
vnd0: not in usevnd0 detached

vnd1: not in use
vnd2: not in use
vnd3: not in use
# vnconfig -u vnd0
vnd0: vnode disk driver
vnconfig: /dev/rvnd0c: VNDvnd0 detached
IOCCLR: Device not configured
# 

>Fix:

Print messages only if VNDIOCSET or VNDIOCCLR is succeeded?
