radeonsi: add return value to gfx10_ngg_calculate_subgroup_info

Browse Source 
gfx10_ngg_calculate_subgroup_info uses assert to detect invalid configuration,
but if asserts are disabled it will continue its execution.

This commits adds a boolean return value to let the caller know that something
went wrong and that the results mustn't be used.
