radv/gfx10: fix required ballot size with VK_EXT_subgroup_size_control

Browse Source 
If compute shaders require a specific subgroup size (ie. Wave32),
we have to use the correct ballot size.

Fixes dEQP-VK.subgroups.ballot_other.compute.*_requiredsubgroupSize.

Fixes: fb07fd4e6c ("radv: implement VK_EXT_subgroup_size_control")
