Steps to reproduce:
1. Compile, install, configure and start an IPMI simulator from OpenIPMI source code to see some sensors with 'ipmitool':

$ ipmitool -U ipmiusr -P test -H 127.0.0.1 -p 9001 -I lanplus -L administrator sensor list
Unable to Get Channel Cipher Suites

2. Create an IPMI test host in Zabbix frontend (see attachment zbx_export_ipmi_host.xml).
Note IPMI settings:

Authentication algorithm: Default
Privilege level: Admin
Username: ipmiusr
Password: test

 Enable only one 'MBTemp' sensor.
3. Make sure the IPMI simulator is running.
4. Run Zabbix server.
For some reason authentification fails between Zabbix server and IPMI simulator.
The IPMI host in Zabbix frontend turns red with error message "cannot connect to IPMI host: [22] Invalid argument'".
5. Stop IPMI simulator.

Result:
The IPMI host in Zabbix frontend turns green and error messages get stored as item values:
2024-05-14 10:37:19 cannot connect to IPMI host: [22] Invalid argument
2024-05-14 10:38:05 cannot connect to IPMI host: [16777411] Unknown error 16777411

Expected:
IPMI host in Zabbix frontend stays red with some error message, no data values in history.
