Tested.  With the replay target that reposts an SRP_RSP for a command it
has already answered, the crash appears in 5 of 5 runs on an unpatched
kernel and in 0 of 5 with your patch.  The target still delivered about
2680 unsolicited responses per run either way, so what went away is the
window, not the traffic.

I have sent your patch as 2/2 of a v2 series on linux-rdma:

Martin, please drop this patch.  The lookup it guards is not reachable
once srp_remove_target() is fixed, and the review point that the check is
lockless stands.
