Description of problem: 1. make sure cnic dev is registered: When using iface, bnx2i was unable to offload further connections after all active sessions are logged out. bnx2i will unregister the device from cnic when the last connection is torn down. Next call to ep_connect() will fail because the device is not registered. This issue is not seen if shost == NULL is passed to ep_connect() call because in that case bnx2i will registers all known devices with cnic before doing a route look-up. When shost != NULL, bnx2i knows the device on which to offload the connection and has to register this device before attempting to offload the connection 2. fix libiscsi eh abort locking iscsi_eh_abort needs to grab the session lock and disable bhs, because the session lock can be taken from a timer or softirq.
