[ofa-general] [PATCH v2] IB/iSER: Release connection resources when receiving a RDMA_CM_EVENT_DEVICE_REMOVAL event

[Erez Zilber]

When a RDMA_CM_EVENT_DEVICE_REMOVAL event is raised, iSER should release the
connection resources.

This is necessary when the IB HCA module is unloaded while open-iscsi is still
running. Currently, iSER just initiates a BUG() call.
