Chuck Lever f5778c2d65 xprtrdma: Fix corner cases when handling device removal ... commit 2552428863 upstream. Michal Kalderon has found some corner cases around device unload with active NFS mounts that I didn't have the imagination to test when xprtrdma device removal was added last year. - The ULP device removal handler is responsible for deallocating the PD. That wasn't clear to me initially, and my own testing suggested it was not necessary, but that is incorrect. - The transport destruction path can no longer assume that there is a valid ID. - When destroying a transport, ensure that ib_free_cq() is not invoked on a CQ that was already released.
