Always wrap up call to dracut get_persistent_dev function 

Dracut get_persistent_dev function don't recognize UUID= or LABEL=
format, so caller should conver it to the path to the block device
before calling it. There is already such a helper
"kdump_get_persistent_dev", just move it to kdump-lib.sh and rename
it to reuse it,
