merge: disable `m2-vs-ma` optimization if new filenode config is true
The `m2-vs-ma` optimization filters out the file which have not changed between
second parent and the ancestor of the merge. This results in the m1-vs-m2 diff
not processing those files. These files will be required when we are creating
new filenode for salvaged cases as we need to track them to store in mergestate
that file can be salvaged.
