setup: don't modify repo in `create_reference_database()`
The `create_reference_database()` function is used to create the
reference database during initialization of a repository. The function
calls `repo_set_ref_storage_format()` to set the repositories reference
format. This is an unexpected side-effect of the function. More so
because the function is only called in two locations:
1. During git-init(1) where the value is propagated from the `struct
repository_format repo_fmt` value.
2. During git-clone(1) where the value is propagated from the
`the_repository` value.
The former is valid, however the flow already calls
`repo_set_ref_storage_format()`, so this effort is simply duplicated.
The latter sets the existing value in `the_repository` back to itself.
While this is okay for now, introduction of more fields in
`repo_set_ref_storage_format()` would cause issues, especially
dynamically allocated strings, where we would free/allocate the same
string back into `the_repostiory`.
To avoid all this confusion, clean up the function to no longer take in
and set the repo's reference storage format.
