HID: nintendo: fix rumble worker null pointer deref
We can dereference a null pointer trying to queue work to a destroyed
workqueue.
If the device is disconnected, nintendo_hid_remove is called, in which
the rumble_queue is destroyed. Avoid using that queue to defer rumble
work once the controller state is set to JOYCON_CTLR_STATE_REMOVED.
This eliminates the null pointer dereference.
