Pull the part of vma_expand() which actually commits the merge operation,
that is inserts it into the maple tree and sets the VMA's vma->vm_start
and vma->vm_end parameters, into its own function.
We implement only the parts needed for vma_expand() which now as a result
of previous work is also the means by which new VMA ranges are merged.
The next commit in the series will implement merging of existing ranges
which will extend commit_merge() to accommodate this case and result in
all merges using this common code.
