[PATCH] cpupower: Combine two condition checks into one statement in get_cpu_topology()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>

The same assignments were used in an if branch of two separate statements.

* Merge their condition checks into a single statement instead.

* Adjust the indentation there.

This issue was detected by using the Coccinelle software.
