wifi: mwifiex: Use IRQF_NO_AUTOEN flag in request_irq()

Browse source 
[ Upstream commit 9a98dd48b6d834d7a3fe5e8e7b8c3a1d006f9685 ]

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.
