After pipe_grid_info.indirect was introduced, clover was not modified
to set it causing it to pass uninitialized memory for it to launch_grid.

This commit fixes this by zero-ing the entire pipe_grid_info struct when
declaring it, to avoid similar problems popping-up in the future.

Messed up the subject prefix, sorry. Resending with proper prefix.
