[PATCH v6 1/3] fetch: use goto cleanup in cmd_fetch()

[Glen Choo <chooglen@google.com>]

Replace an early return with 'goto cleanup' in cmd_fetch() so that the
string_list is always cleared (the string_list_clear() call is purely
cleanup; the string_list is not reused). This makes cleanup consistent
so that a subsequent commit can use 'goto cleanup' to bail out early.
