genirq: Set IRQF_COND_ONESHOT in request_irq()

The callers of request_irq() don't care about IRQF_ONESHOT because they
don't provide threaded handlers, but if they happen to share the IRQ with
the ACPI SCI, which has a threaded handler and sets IRQF_ONESHOT,
request_irq() will fail for them due to a flags mismatch.

Address this by making request_irq() add IRQF_COND_ONESHOT to the flags
passed to request_threaded_irq() for all of its callers.
