Before b152d26 it was possible to set iscsi->reconnect_max_retries to 0.
This allowed reconnects, but aborted as soon as the reconnect failed.
The same behaviour is currenltly only possible by setting iscsi->reconnect_max_retries
to 1. iscsi->reconnect_max_retries == 0 forbids reconnecting completly.
