    Don't check fs modified when dump target is lvm2 thinp

    When the dump target is lvm2 thinp, if we didn't mount
    the dump target first, get_fs_type_from_target will get
    empty output:

    Before mount:
    $ get_fs_type_from_target /dev/vg00/thinlv

    After mount:
    $ mount /dev/vg00/thinlv /mnt
    $ get_fs_type_from_target /dev/vg00/thinlv
    ext4

    As a result, kdumpctl start will fail with:
    $ kdumpctl start
    kdump: Dump target is invalid
    kdump: Starting kdump: [FAILED]

    This patch fix the issue by bypassing check_fs_modified
    when the dump target is lvm2 thinp.
