minios: clean up unneeded "err = NULL" in frontend drivers
This patch removes cases where the error message pointer is already NULL and is then set to NULL. These are harmless, but suggest incorrect practice: the pointer should be passed to free() to deallocate memory prior to reassignment. There are no functional changes in this patch.
