kernel: virtio_pmem: add the missing REQ_OP_WRITE for flush bio

A flaw was discovered in the virtiopmem driver in the Linux kernel, where flush block I/O requests did not have the required REQOPWRITE operation code assigned before submission. Under workloads involving persistent memory block devices — for example, running mkfs.xfs on a pmem device,this omissi...
