Dan Carpenter 7030a7e932 x86/cpu/amd: Remove an unneeded condition in srat_detect_node() 
Originally we calculated ht_nodeid as "ht_nodeid = apicid -
boot_cpu_id;" so presumably it could be negative.

But after commit:

  01aaea1afb ('x86: introduce initial apicid')

we use c->initial_apicid which is an unsigned short and thus always >= 0.

It causes a static checker warning to test for impossible
conditions so let's remove it.
