ASoC: wm8994: Pass the IRQF_ONESHOT flag

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.

So pass the IRQF_ONESHOT flag in this case.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/irqf_oneshot.cocci.
