MDEV-23445: LIMIT ROWS EXAMINED throws error in Debug build only

Browse Source 
Analysis: When we reach the maximum limit to examine rows killed_state is set
as ABORT. But this isn't an actual error and we still return TRUE. This
eventually sets error as UNKNOWN ERROR.
Fix: Check if need to stop execution by checking the killed state. If we have
to abort it, return false because this isn't an actual error.
