[PATCH 3/7] builtin/send-pack.c: stop using `the_repository`

[Usman Akinyemi <usmanakinyemi202@gmail.com>]

Remove the_repository global variable in favor of the repository
argument that gets passed in "builtin/send-pack.c".

When `-h` is passed to the command outside a Git repository, the
`run_builtin()` will call the `cmd_send_pack()` function with `repo` set
to NULL and then early in the function, `parse_options()` call will give
the options help and exit, without having to consult much of the
configuration file. So it is safe to omit reading the config when `repo`
argument the caller gave us is NULL.
