[LU-3253] MDT objects are not really MD objects

• Type: Bug

Description

There is currently no reason for struct mdt_object to include a md_object when it can just use an lu_object instead. Same for struct mdt_device. Switching from md_object to lu_object saves 16 bytes and makes for more concise code.
