From: Johannes Schindelin <johannes.schindelin@gmx.de>

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.
