drivers:md: Remove unneeded fix me comments in dm-bio-prison.h

Removes two unneeded fix me comments for removing the header files, persistent-data/dm-block-manager.h and dm-thin-metadata.h. These headers are needed in order to build this file successfully and for it to run,thus the comments should be removed as they are no longer needed.
