virtio: Clear interrupt status register in virtio-blk The VRING_AVAIL_F_NO_INTERRUPT flag is a hint that interrupts should be suppressed. It does not guarantee that interrupts will not be raised. Therefore, make sure to clear the interrupt after each virtio-blk read. This avoids a stuck interrupt interfering with the OS loaded later in the boot process.
