v3d: Always set up the qregs for CSD payload.
We were failing to set up payload[1] for use by LocalInvocationIndex/ID and shared variable accesses if gl_WorkGroupID/gl_GlobalInvocationID wasn't used (possibly because you only have one workgroup). You're always going to use payload[1], and payload[0] is common enough and we have DCE in the backend to clean it up if it happens to not be used.
