If tag following is required when using a transport that does not
support tag following, fetch_pack() will be invoked twice in the same
process, necessitating a clearing of the object flags used by
fetch_pack() sometime during the second invocation. This is currently
done in find_common(), which means that the work done by
everything_local() in marking complete remote refs as COMMON_REF is
wasted.
To avoid this wastage, move this clearing from find_common() to its
parent function do_fetch_pack(), right before it calls
everything_local().
This has been occurring since the commit that introduced the clearing of
marks, 420e9af498 ("Fix tag following", 2008-03-19).
The corresponding code for protocol v2 in do_fetch_pack_v2() does not
have this problem, as the clearing of flags is done before any marking
(whether by rev_list_insert_ref_oid() or everything_local()).
