Daniel J. Ogorchock 7c6e6c3341 HID: nintendo: fix rumble worker null pointer deref
commit 1ff89e06c2 upstream.

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.
