[PATCH 1/3] ACPI / processor: remove incorrect comparison of phys_id

[Sudeep Holla <sudeep.holla@arm.com>]

phys_id in acpi_processor structure is unsigned 32-bit integer,
comparing it with signed value is incorrect.

This patch removes that incorrect comparision in acpi_processor_hotadd_init
as the lone user of this function is already checking for correctness
of phys_id before calling it.
