perf/x86/intel/uncore: Fix missing marker for snr_uncore_imc_freerunning_events

BugLink: https://bugs.launchpad.net/bugs/1862429
commit fa694ae532836bd2f4cd659e9b4032abaf9fa9e5 upstream.

An Oops during the boot is found on some SNR machines.  It turns out
this is because the snr_uncore_imc_freerunning_events[] array was
missing an end-marker.
