nvme-rdma: fix potential unbalanced freeze & unfreeze
Move start_freeze into nvme_rdma_configure_io_queues(), and there is
at least two benefits:
1) fix unbalanced freeze and unfreeze, since re-connection work may
fail or be broken by removal
2) IO during error recovery can be failfast quickly because nvme fabrics
unquiesces queues after teardown.
One side-effect is that !mpath request may timeout during connecting
because of queue topo change, but that looks not one big deal:
1) same problem exists with current code base
2) compared with !mpath, mpath use case is dominant
