Subject: [PATCH wireless v2 2/3] wifi: mwifiex: Use IRQF_NO_AUTOEN flag in request_irq()

disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable when request IRQ.

Fixes: 853402a00823 ("mwifiex: Enable WoWLAN for both sdio and pcie")
