[PATCH v5 06/15] submodule--helper: die on config error when cloning module

[Patrick Steinhardt <ps@pks.im>]

When setting the 'core.worktree' option for a newly cloned
submodule we ignore the return value of `git_config_set_in_file`.
As this leaves the submodule in an inconsistent state, we instead
want to inform the user that something has gone wrong by printing
an error and aborting the program.
