etnaviv: Clear lbl_usage array correctly
Fill the entire array instead of just a quarter. This avoids crashes with large shaders. (currently this never causes a problem because shaders larger than 2048/4 instructions are not supported by this driver on any hardware, but it will cause problems in the future) Fixes: ec436051 ("etnaviv: fix shader miscompilation with more than 16 labels") Cc: mesa-stable@lists.freedesktop.org Signed-off-by:Wladimir J. van der Laan <laanwj@gmail.com> Reviewed-by:
