mm: make the vma list be doubly linked
commit 297c5eee372478fc32fec5fe8eed711eedb13f3d upstream. It's a really simple list, and several of the users want to go backwards in it to find the previous vma. So rather than have to look up the previous entry with 'find_vma_prev()' or something similar, just make it doubly linked instead.
