x86/apic: Remove the pointless writeback of boot_cpu_physical_apicid
There is absolutely no point to write the APIC ID which was read from the
local APIC earlier, back into the local APIC for the 64-bit UP case.
Remove that along with the apic callback which is solely there for this
pointless exercise.
