Subject: nvme-rdma: change queue flag semantics DELETING -> ALLOCATED
Patch-mainline: v4.15-rc1
Git-commit: 5013e98b5e8db50144e8f1ca5a96aed95d4d48a0
References: FATE#323952, FATE#322506

Instead of marking we are deleting, mark we are allocated and check that
instead. This makes the logic symmetrical to connected mark check.
