When constructing arguments to pass to setup_revision(), pack-objects
only frees the memory used by that array after calling
get_object_list().
Ensure that we call strvec_clear() whether or not we use the arguments
array by cleaning up whenever we exit the function (and rewriting one
early return to jump to a label which frees the memory and then
returns).
We could avoid setting this array up altogether unless we are in the
if-else block that calls get_object_list(), but setting up the argument
array is intermingled with lots of other side-effects, e.g.:
if (exclude_promisor_objects) {
use_internal_rev_list = 1;
fetch_if_missing = 0;
strvec_push(&rp, "--exclude-promisor-objects");
}
So it would be awkward to check exclude_promisor_objects twice: first to
set use_internal_rev_list and fetch_if_missing, and then again above
get_object_list() to push the relevant argument onto the array.
Instead, leave the array's construction alone and make sure to free it
unconditionally.
