"Server_IO_State" field

Critical error messages from get_master_version_and_clock() were written
only to the slave errorlog while Show slave status did not display any
incident happened.

Although the artifact was reported for a particular --replicate-same-server-id
related issue the fix refines all critical error reporting with 
deploying rli->report().

The test for the bug covers only --replicate-same-server-id error reporting.
