[PATCH 2/7] net: enetc: Use IRQF_NO_AUTOEN flag in request_irq()

[Jinjie Ruan]

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: bbb96dc7fa1a ("enetc: Factor out the traffic start/stop procedures")
