HID: hid-steam: Don't use cancel_delayed_work_sync in IRQ context

Browse source 
Lockdep reported that, as steam_do_deck_input_event is called from
steam_raw_event inside of an IRQ context, it can lead to issues if that IRQ
occurs while the work to be cancelled is running. By using cancel_delayed_work,
this issue can be avoided. The exact ordering of the work and the event
processing is not super important, so this is safe.
