drm/msm/adreno: Use IRQF_NO_AUTOEN flag in request_irq()

Browse source 
[ Upstream commit 394679f322649d06fea3c646ba65f5a0887f52c3 ]

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.
