[IB] uverbs: Avoid NULL pointer deref on CQ async event
Userspace CQs that have no completion event channel attached end up with their cq_context set to NULL. However, asynchronous events like "CQ overrun" can still occur on such CQs, so add a uverbs_file member to struct ib_ucq_object that we can follow to deliver these events.
