perf/x86/uncore: Fix missing end markers for SNB/IVB/HSW IMC PMU

Browse Source 
This patch fixes a bug with the SNB/IVB/HSW uncore
mmeory controller support.

The PCI Ids tables for the memory controller were missing end
markers. That could cause random crashes on boot during or after
PCI device registration.
