[PATCH 6.1 0764/1146] perf stat: Use evsel__is_hybrid() more

From: Namhyung Kim <namhyung@kernel.org>

[ Upstream commit 93d5e700156e03e66eb1bf2158ba3b8a8b354c71 ]

In the stat-display code, it needs to check if the current evsel is
hybrid but it uses perf_pmu__has_hybrid() which can return true for
non-hybrid event too. I think it's better to use evsel__is_hybrid().

Also remove a NULL check for the 'config' parameter in the
hybrid_merge() since it's called after config->no_merge check.
