Chaitanya Kulkarni e9c78c2335 nvme-pci: remove the barriers in nvme_irq() ... The barriers were added to the nvme_irq() in commit 3a7afd8ee4 ("nvme-pci: remove the CQ lock for interrupt driven queues") to prevent compiler from doing memory optimization for the variabes that were protected previously by spinlock in nvme_irq() at completion queue processing and with queue head check condition. The variable nvmeq->last_cq_head from those checks was removed in the commit f6c4d97b0d ("nvme/pci: Remove last_cq_head") that was not allwing poll queues from mistakenly triggering the spurious interrupt detection. Remove the barriers which were protecting the updates to the variables.
