Log Message:
Putting a device into the unconfigured state by an ioctl seems legitimate,
so check for a non-NULL configuration descriptor before dereferencing.
Should fix a crash reported by Nicolas Joly per PR kern/41048.
(It still doesn't look good that the ioctl which unconfigures the device
returns EIO -- either it is legitimate or it isn't -- but since this
is a pullup candidate I don't dare to change user visible behaviour.)
