usb gadget: g_ether spinlock recursion fix
The new spinlock debug code turned up a spinlock recursion bug in the Ethernet gadget driver on a disconnect path; it would show up with any UDC driver where the cancellation of active requests was synchronous, rather than e.g. delayed until a controller's completion IRQ. That recursion is fixed here by creating and using a new spinlock to protect the relevant lists.
