[Patch v7 4/6] store the default dump target info when default target is a separate disk

If default target is a separate disk, the related information need be stored in /etc/kdump.conf of kdump initramfs. This includes the disk info which will help to deduce the dump_code and path which the vmcore will be written into. v5->v7: No v6 for this patch. Just use newly introduced function is_fs_type_nfs in default_dump_target_install_conf().
