mm: abstract vma_expand() to use vma_merge_struct
The purpose of the vmg is to thread merge state through functions and
avoid egregious parameter lists. We expand this to vma_expand(), which is
used for a number of merge cases.
Accordingly, adjust its callers, mmap_region() and relocate_vma_down(), to
use a vmg.
An added purpose of this change is the ability in a future commit to
perform all new VMA range merging using vma_expand().
