Kiryl Shutsemau f0369fb136 mm: change the interface of prep_compound_tail() 
Instead of passing down the head page and tail page index, pass the tail
and head pages directly, as well as the order of the compound page.

This is a preparation for changing how the head position is encoded in the
tail page.
