scsi: mpt3sas: Don't call disable_irq from IRQ poll handler
disable_irq() might sleep, replace it with disable_irq_nosync(). For synchronisation 'irq_poll_scheduled' is sufficient Fixes: 320e77acb3 scsi: mpt3sas: Irq poll to avoid CPU hard lockups Link: https://lore.kernel.org/r/20200901145026.12174-1-thenzl@redhat.com Signed-off-by: Tomas Henzl <thenzl@redhat.com> Signed-off-by: Martin K.
