glx: Stop tracking hasUnflushedCommands
This is only meaningful for indirect contexts, and all it does is (maybe) prevent a flush when switching away from an indirect context. Indirect contexts aren't worth optimizing for, and Mesa tracks whether a flush is needed anyway. Careful readers will note that ReadPixels would reset the flag even though it doesn't imply a flush!
