Bug #23295288: HANDLE_FATAL_SIGNAL (SIG=11) IN

Browse Source 
GET_SERVER_FROM_TABLE_TO_CACHE

Description:- Server received SIG11 in the function,
"get_server_from_table_to_cache()".

Analysis:- Defining a server with a blank name is not
handled properly.

Fix:- Modified "get_server_from_table_to_cache()" to
take care of blank server name.
