In update_submodules, we use the run_processes_parallel(get_task, finished)
API, which allows to pass around a task specific callback cookie from the
get_next function to the finish function. That finish function in turn may
alter generic callback cookie to have the next call of get_task come up
with another new task.
Up to now we passed around the index into a list of cache entries,
which was stored in the generic callback cookie which is a struct
submodule_update_clone.
Change this to an index into 'update_clone' array, which is the potential
output of this helper. This will allow for a future change to make
use of the data the update_clone_data struct.
