[PATCH] cpufreq: Drop unnecessary check from cpufreq_policy_alloc()

["Rafael J. Wysocki" <rjw@rjwysocki.net>]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Since cpufreq_policy_alloc() doesn't use its dev variable for
anything useful, drop that variable from there along with the
NULL check against it.
