Subject: [PATCH] usbfs: don't store bad pointers in registration

This patch (as1107) fixes a small bug in the usbfs registration and
unregistration code.  It avoids leaving an error value stored in the
device's usb_classdev field and it avoids trying to unregister a NULL
pointer.  (It also fixes a rather extreme overuse of whitespace.)
