[PATCH] scsi: iscsi: start endpoint ID allocation from 1

[Varun Prakash <varun@xxxxxxxxxxx>]

ktransport_ep_connect() (defined in open-iscsi/usr/netlink.c)
returns -EIO if endpoint ID is 0.

int
ktransport_ep_connect(iscsi_conn_t *conn, int non_blocking)
{
	...
	rc = __kipc_call(iov, 2);
	if (rc < 0)
		return rc;

	if (!ev->r.ep_connect_ret.handle)
		return -EIO;

	conn->transport_ep_handle = ev->r.ep_connect_ret.handle;
	...
}
