intelmetool: Comment out unused variable

Only commented out code uses the variable `csr`, and GCC complains about
it, when enabling the warning *unused-but-set-variable*.

```
Checking for pciutils and zlib... me.c: In function ‘mei_dump’:
me.c:50:18: warning: variable ‘csr’ set but not used [-Wunused-but-set-variable]
  struct mei_csr *csr;
                  ^~~
```

As the code is commented, also comment out the declaration of the variable.
