[PATCH v2 6/7] remote-curl: use http_fetch_ref() instead of walker wrapper

[Tay Ray Chuan <rctay89@gmail.com>]

The http-walker implementation of walker->fetch_ref() doesn't do
anything special compared to http_fetch_ref() anyway.

Remove init_walker() invocation before fetching the ref, since we aren't
using the walker wrapper and don't need a walker instance anymore.
