[patch] x86/AMD: remove an unneeded condition in srat_detect_node()

[Dan Carpenter]

Originally we calculated ht_nodeid as "ht_nodeid = apicid - boot_cpu_id;"
so presumably it could be negative.  But after commit 01aaea1afbcd
('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.
