What's the need for the assignment, out of curiosity?

It shuts up a gcc warning about how the dquot pointer is set but never
used.  One hopes the same gcc is smart enough not to generate any code
for this.

The alternative would be to turn these stubs into inline functions,
which would also kill the warning.
