virtio_pmem: Check device status before requesting flush
If a pmem device is in a bad status, the driver side could wait for
host ack forever in virtio_pmem_flush(), causing the system to hang.
So add a status check in the beginning of virtio_pmem_flush() to return
early if the device is not activated.
