intel_pstate: Simplify conditional in intel_pstate_set_policy()
One of the if () statements in intel_pstate_set_policy() causes another if () to be evaluated if the condition is true and it doesn't do anything else, so merge the two if () statements into one. No functional changes. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
