Alan Stern 45f785a21a usb: gadget: fix a bug and a WARN_ON in dummy-hcd ...

commit 5f5610f69b upstream.

This patch fixes a NULL pointer dereference and a WARN_ON in
dummy-hcd.  These things were the result of moving to the UDC core
framework, and possibly of changes to that framework.

Now unloading a gadget driver causes the UDC to be stopped after the
gadget driver is unbound, not before.  Therefore the "driver" argument
to dummy_udc_stop() can be NULL, so we must not try to print the
driver's name without checking first.

Also, the UDC framework automatically unregisters the gadget when the
UDC is deleted.  Therefore a sysfs attribute file attached to the
gadget must be removed before the UDC is deleted, not after.
