rpcrdma: fix handling for RDMA_CM_EVENT_DEVICE_REMOVAL
Under the scenario of IB device bonding, when bringing down one of the
ports, or all ports, we saw xprtrdma entering a non-recoverable state
where it is not even possible to complete the disconnect and shut it
down the mount, requiring a reboot. Following debug, we saw that
transport connect never ended after receiving the
RDMA_CM_EVENT_DEVICE_REMOVAL callback.
The DEVICE_REMOVAL callback is irrespective of whether the CM_ID is
connected, and ESTABLISHED may not have happened. So need to work with
each of these states accordingly.
