acpi/processor: Check for duplicate processor ids at hotplug time

Browse Source 
The check for duplicate processor ids happens at boot time based on the
ACPI table contents, but the final sanity checks for a processor happen
at hotplug time.

At hotplug time, where the physical information is available, which might
differ from the ACPI table information, a check for duplicate processor
ids is missing.

Add it to the hotplug checks and rename the function so it better
reflects its purpose.
