lis3lv02d: Omit IRQF_ONESHOT if no threaded handler is provided

Browse Source 
The lis3lv02d started triggering a WARN in the IRQ code because it
passes IRQF_ONESHOT to request_threaded_irq() even when thread_fn is
NULL, which is an invalid combination.

So set the flag only if thread_fn is non-NULL.
