Revert "mkdumprd: omit dracut modules in case of no dm target"

Browse Source 
This reverts commit 821d1af080.

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.
