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.
