radv/gfx10: fix required ballot size with VK_EXT_subgroup_size_control
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: fb07fd4e6cb ("radv: implement VK_EXT_subgroup_size_control")
