drm/amdkfd: fix a bug of smi event for superuser

Browse Source 
rocm-smi with superuser permission doesn't show some
of smi events, i.e. page fault/migration, because the
condition of "(events & all)" is false. Superuser
should be able to detect all events, the condiiton of
"(events & all)" seems redundant, so removing it will
fix the issue.
