Revert "mkdumprd: omit crypt when there is no crypt kdump target"

This reverts commit 54a5bcc4ee.

We are going to add "--no-hostonly-default-device" dracut argument
in the following patch.

With the help of "--no-hostonly-default-device", dracut only
adds the dump target as host devices, which naturally guarantees
only required dracut modules being selected.
