[PATCH] iscsi class: quiet iscsi_add_session compilation warning.

[Mike Christie]

If ISCSI_MAX_TARGET was zero then iscsi_add_session could return
success when it had failed. This will currently not happen because
ISCSI_MAX_TARGET is a macro and not a variable. But gcc likes to
complain about it and people keep reporting it. This patch
just initializes err to be -EINVAL so if we ever defined
ISCSI_MAX_TARGET incorrectly we would fail gracefully.
