USB: g_printer: fix bug in unregistration
commit 8582d86143c690c68cc42f996def466a035bee34 upstream.
The allocated chardevice region range is only 1 device but on
unregister it currently tries to deregister 2.
Found this while doing a insmod/rmmod/insmod/rm... of the module
which seemed to eat major numbers.
