largefiles: remove redundant checks for false modify/delete conflicts

In a34a99181f36 (largefiles: don't show largefile/normal prompts if
one side is unchanged, 2014-12-01), overridecalculateupdates() started
checking for false modify/delete conflicts in large files and their
standins. Then, in the very next changeset, 902554884335 (merge:
before cd/dc prompt, check that changed side really changed,
2014-12-01), calculateupdates() itself started checking for false
modify/delete conflicts in all files. Since "large files and their
standins" is a subset of "all files", we can now drop the checks in
overridecalculateupdates().
