largefiles: remove unused assignments from wrapfunction()

The return values from wrapfunction() were never used here. Using the
value is also a little tricky and wrappedfunction() should be
preferred, so let's just delete the assignments.

There's also a bunch of return values from wrapcommand() being
assigned to a variable here, but at least that value can be (and is
used after some of the assignments).
