[PATCH 08/14] remote-curl: free "discovery" object

[Jeff King <peff@peff.net>]

We cache the last-used "discovery" object, which contains
the data we pulled from the remote about which refs it has,
which saves us an HTTP round-trip when somebody does
something like "list" followed by "fetch".

We don't bother free()ing it at the end of the program
because it just contains memory which will be reclaimed by
the OS. However, cleaning up explicitly will future-proof us
against later changes which will add external storage (like
temporary files).
