[PATCH] driver core: Don't remove kobjects in device_shutdown.

[ebiederm@xmission.com (Eric W. Biederman)]

device_shutdown is defined to just shutdown the hardware and to not
clean up any kernel data structures.  Therefore don't put the kobjects
for /sys/dev and /sys/dev/block and /sys/dev/char.

This ensures we don't remove /sys/dev/block and /sys/dev/char while
we still have symlinks from there to the actual devices.
