[PATCH 6.12] tools/power turbostat: Fix compilation on older compilers

[Nikolay Kuratov]

Currently turbostat.c can't be built on pre-gcc-11 compilers
due to error: a label can only be part of a statement and a declaration
is not a statement.

Fix this by adding braces around case labels.

Fixes: 640540beb883 ("tools/power turbostat: Add MTL's PMT DC6 builtin counter")
