[PATCH] submodule: do no re-read name in shell script

[PATCH] submodule: do no re-read name in shell script

[Stefan Beller]

Instead of making another call to a submodule helper (name), just
propagate the value when we know it (in the update-clone helper) already.

Are there any restrictions on what characters a submodule name can
contain?  Does this need e.g. to be quoted with sq_quote?

Oh good point, this ought to fail with weird names. So instead of quoting it,
let's just drop this patch.
