update-ref: drop unused argument for `parse_refname`

The `parse_refname` function accepts a `struct strbuf *input` argument
that isn't used at all. As we're about to convert commands to not use a
strbuf anymore but instead an end pointer, let's drop this argument now
to make the converting commit easier to review.
