Not used import in django.db

[vorushin]

I found in django/db/init.py import that is not used there at the moment:

from django.utils.functional import curry

I applied removed this sting and ran django tests - everything worked without errors. Patch, removing this unused import, is attached to this ticket.

Generally, cleanup patches like this aren't accepted because they just introduce code churn. We'll fix this the next time someone's in that file; it's not worth keeping a ticket around for.
