scsi: megaraid_sas: Don't call disable_irq from process IRQ poll
[ Upstream commit d2af39141eea34ef651961e885f49d96781a1016 ]
disable_irq() might sleep. Replace it with disable_irq_nosync() which is
sufficient as irq_poll_scheduled protects against concurrently running
complete_cmd_fusion() from megasas_irqpoll() and megasas_isr_fusion().
