Actually, what I think may be useful are calls similar to:

ib_sa_cancel_queries(struct ib_sa_client *, struct ib_device *);

ib_sa_cancel_all(struct ib_sa_client *);

However, until I can finish the userspace SA client support, I won't know what
the best API would be.

Tracking queries by every user seems redundant.
