[PATCH v3] parse-remote: remove reference to unused op_prep

[Siddharth Kannan <kannan.siddharth12@gmail.com>]

The error_on_missing_default_upstream helper function learned to
take op_prep argument with 15a147e618 ("rebase: use @{upstream}
if no upstream specified", 2011-02-09), but as of 045fac5845
("i18n: git-parse-remote.sh: mark strings for translation",
 2016-04-19), the argument is no longer used.  Remove it.

Thanks a lot for the review, Pranit and Junio! I have made the appropriate
changes, and the edit to the file inside contrib/examples/ has been removed from
this patch.
