The existing apic_id = cpu_index code has no visible effect: the PC code
already initializes the APIC ID according to the topology on
pc_new_cpu(), and linux-user memcpy()s the CPU state (including
cpuid_apic_id) on cpu_copy().

Remove the dead code and simply let APIC ID to to be 0 by default. This
doesn't change behavior of PC because apic-id is already explicitly set,
and doesn't affect linux-user because APIC ID was already always 0.
