Philip Chen 0da7dd9adf virtio_pmem: Check device status before requesting flush
[ Upstream commit e25fbcd97cf52c3c9824d44b5c56c19673c3dd50 ]

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.
