pvr: fix pvr_clear_vdm_state_get_size_in_dw() inverted feature condition

Browse source 
The pvr_clear_vdm_state_get_size_in_dw() wrongly think instance count
inputs are needed when doing RTA clear for cores without the
gs_rta_support feature. However, the instance ID is exploited to output
the target layer ID, which isn't supported at all for cores w/o that
feature, so it looks that the condition is inverted. In addition, the
pvr_pack_clear_vdm_state() function seems to have similar logic deciding
whether to emit instance_count, and the logic is opposite to the logic
in pvr_clear_vdm_state_get_size_in_dw() for the part checking the
gs_rta_support feature.

Invert the condition to take instance ID inputs for cores with the
gs_rta_support feature instead of those without this feature.
