Incorrect argument while retrieving quota with project and user in DbQuotaDriver

[Tianpeng Wang]

The `user_id` passed in db.quota_get() should be a keyword argument.

The prototype of quota_get():

def quota_get(context, project_id, resource, user_id=None)

But In DbQuotaDriver::get_by_project_and_user():

return db.quota_get(context, project_id, user_id, resource)

which should be:

return db.quota_get(context, project_id, resource, user_id=user_id)

    Fix incorrect argument position in DbQuotaDriver

    The prototype of db.quota_get is:
    `quota_get(context, project_id, resource, user_id=None)`
    However, in DbQuotaDriver::get_by_project_and_user(), the `user_id`
    is incorrectly used as a positional argument.
