Peter Zijlstra 7dce450ca8 perf: Fix event multiplexing for exclusive groups ...

[ Upstream commit 2714c3962f ]

Commit 9e6302056f ("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.
