svga: fix clip plane regression after recent tgsi_scan change
Before the change "tgsi/scan: use properties for clip/cull distance writemasks", the tgsi_shader_info::num_written_clipdistance field was a multiple of four, now it's an accurate count. In the svga driver, we need a minor change to the loop test. Reviewed-by: Charmaine Lee <charmainel@vmware.com>
