WANG Chao 43da5c516d mkdumprd: get_persistent_dev() return original dev if no persistent dev exists.
kvm virtio-blk device, for example /dev/vdb, doesn't have serial id by
default. So there's no persistent device node under /dev/disk/ for
/dev/vdb.
In case no persistent dev for dump target, we should use the original
device name directly, not failing the mkdumprd.

v2: update warn message from Vivek.
