ruby: remove the function functionalReadBuffers()

This function was added when I had incorrectly arrived at the conclusion
that such a function can improve the chances of a functional read succeeding.
As was later realized, this is not possible in the current setup.  While the
code using this function was dropped long back, this function was not.  Hence
the patch.
