Dan Carpenter a6763625ae 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: 95ed6c707f ("perf/cgroup: Order events in RB tree by cgroup id")
