perf/core: Fix reversed NULL check in perf_event_groups_less()
This NULL check is reversed so it leads to a Smatch warning and
presumably a NULL dereference.
kernel/events/core.c:1598 perf_event_groups_less()
error: we previously assumed 'right->cgrp->css.cgroup' could be null
(see line 1590)
Fixes: 95ed6c707f26 ("perf/cgroup: Order events in RB tree by cgroup id")
