config: don't special-case multivars that don't exist yetcmn/multivar-set-locked

This special-casing ignores that we might have a locked file, so the
hashtable does not represent the contents of the file we want to
write. This causes multivar writes to overwrite entries instead of add
to them when under lock.

There is no need for this as the normal code-path will write to the file
just fine, so simply get rid of it.
