radv: fix crash in shader tracing.
Enabling tracing, and then having a vmfault, can leads to a segfault
before we print out the traces, as if a meta shader is executing
and we don't have the NIR for it.
Just pass the stage and give back a default.
Fixes: 9b9ccee4d64 ("radv: take LDS into account for compute shader occupancy stats")
