intel_pstate: Clean up intel_pstate_get()
intel_pstate_get() contains a local variable that's initialized but never used and it can be written in fewer lines of code, so clean it up. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
