http.c: remove verification of remote packs

Browse Source 
Make http.c::fetch_pack_index() no longer check for the remote pack
with a HEAD request before fetching the corresponding pack index file.

Not only does sending a HEAD request before we do a GET incur a
performance penalty, it does not offer any significant error-
prevention advantages (pack fetching in the *_http_pack_request()
methods is capable of handling any errors on its own).

This addresses an issue raised elsewhere:
