[PATCH 07/11] submodule--helper: avoid memory leak when fetching submodules

From: Johannes Schindelin <redacted>

In c51f8f94e5b3 (submodule--helper: run update procedures from C,
2021-08-24), we added code that first obtains the default remote, and
then adds that to a `strvec`.

However, we never released the default remote's memory.

Reported by Coverity.
