Subject: [PATCH] wfx: fix irqf_oneshot.cocci warnings

From: kernel test robot <lkp@...el.com>

drivers/net/wireless/silabs/wfx/bus_sdio.c:134:8-33: ERROR: Threaded IRQ with no primary handler requested without IRQF_ONESHOT

 Since commit 1c6c69525b40 ("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.
