        src/sys/dev/usb: usbnet.c

Log Message:
in usbnet_detach(), check both that the private pointer has
been allocated and that unp_attached is true before trying
to access anything else.

fixes a detach problem noticed by maxv when, eg, the call
to usbd_set_config_no() fails and attach bails early.
