upload-pack: clear filter_options for each v2 fetch command
Because of the request/response model of protocol v2, the
upload_pack_v2() function is sometimes called twice in the same
process, while 'struct list_objects_filter_options filter_options'
was declared as static at the beginning of 'upload-pack.c'.
This made the check in list_objects_filter_die_if_populated(), which
is called by process_args(), fail the second time upload_pack_v2() is
called, as filter_options had already been populated the first time.
To fix that, filter_options is not static any more. It's now owned
directly by upload_pack(). It's now also part of 'struct
upload_pack_data', so that it's owned indirectly by upload_pack_v2().
In the long term, the goal is to also have upload_pack() use
'struct upload_pack_data', so adding filter_options to this struct
makes more sense than to have it owned directly by upload_pack_v2().
This fixes the first of the 2 bugs documented by d0badf8797
(partial-clone: demonstrate bugs in partial fetch, 2020-02-21).
