perf list: Fix topic and pmu_name argument order
[ Upstream commit d99b3125726aade4f5ec4aae04805134ab4b0abd ]
Fix function definitions to match header file declaration. Fix two
callers to pass the arguments in the right order.
On Intel Tigerlake, before:
```
$ perf list -j|grep "\"Topic\""|sort|uniq
"Topic": "cache",
"Topic": "cpu",
"Topic": "floating point",
"Topic": "frontend",
"Topic": "memory",
"Topic": "other",
"Topic": "pfm icl",
"Topic": "pfm ix86arch",
"Topic": "pfm perf_raw",
"Topic": "pipeline",
"Topic": "tool",
"Topic": "uncore interconnect",
"Topic": "uncore memory",
"Topic": "uncore other",
"Topic": "virtual memory",
$ perf list -j|grep "\"Unit\""|sort|uniq
"Unit": "cache",
"Unit": "cpu",
"Unit": "cstate_core",
"Unit": "cstate_pkg",
"Unit": "i915",
"Unit": "icl",
"Unit": "intel_bts",
"Unit": "intel_pt",
"Unit": "ix86arch",
"Unit": "msr",
"Unit": "perf_raw",

"Unit": "uncore_arb",
"Unit": "uncore_clock",
"Unit": "uncore_imc_free_running_0",
"Unit": "uncore_imc_free_running_1",
```
After:
```
$ perf list -j|grep "\"Topic\""|sort|uniq
"Topic": "cache",
"Topic": "floating point",
"Topic": "frontend",
"Topic": "memory",
"Topic": "other",
"Topic": "pfm icl",

"Unit": "cstate_core",
"Unit": "cstate_pkg",
"Unit": "i915",
"Unit": "icl",
"Unit": "intel_bts",
"Unit": "intel_pt",
"Unit": "ix86arch",

"Unit": "perf_raw",
"Unit": "power",

"Unit": "uncore_arb",
