Subject: [PATCH] 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: ec436051899 ("etnaviv: fix shader miscompilation with more than 16 labels")
