perf/smmuv3: Validate groups for global filtering

mainline inclusion
from mainline-v5.3-rc1
commit 3c934735
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4A1XO
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3c9347351a6ea1234aa647b36f89052de050d2a2



------------------------------------------------------------------------

With global filtering, it becomes possible for users to construct
self-contradictory groups with conflicting filters. Make sure we
cover that when initially validating events.
