Jason Gunthorpe 14e23bd6d2 RDMA/core: Fix locking in ib_uverbs_event_read ...

This should not be using ib_dev to test for disassociation, during
disassociation is_closed is set under lock and the waitq is triggered.

Instead check is_closed and be sure to re-obtain the lock to test the
value after the wait_event returns.

Fixes: 036b106357 ("IB/uverbs: Enable device removal when there are active user space applications")
