perf: Fix event multiplexing for exclusive groups
Commit 9e6302056f80 ("perf: Use hrtimers for event multiplexing")
placed the hrtimer (re)start call in the wrong place. Instead of
capturing all scheduling failures, it only considered the PMU failure.
The result is that groups using perf_event_attr::exclusive are no
longer rotated.
