r600: amend space check for chips older than EVERGREEN

Browse source 
evergreen_emit_atomic_buffer_setup_count is only called if chip >= EVERGREEN
otherwise atomic_used_mask is left uninitialized when unconditionally used by
r600_need_cs_space so it might want more space than needed

fix this by always initializing atomic_used_mask
