Alexander Antonov bf1bf09e6b perf/x86/intel/uncore: Fix NULL pointer dereference issue in upi_fill_topology() 
[ Upstream commit 1692cf434b ]

Get logical socket id instead of physical id in discover_upi_topology()
to avoid out-of-bound access on 'upi = &type->topology[nid][idx];' line
that leads to NULL pointer dereference in upi_fill_topology()

Fixes: f680b6e606 ("perf/x86/intel/uncore: Enable UPI topology discovery for Icelake Server")
