[PATCH v3 07/10] power/intel_pstate: remove redundant lcore ID checks

[Huisong Li]

Now that the cpufreq framework validates the lcore ID using
rte_lcore_is_eal_managed() before dispatching to any driver,
each individual cpufreq driver no longer needs its own range
check against RTE_MAX_LCORE.

Remove the duplicated lcore ID checks from the intel_pstate
cpufreq driver ops.
