Subject: perf evsel: Missed close() when probing hybrid core PMUs

[ Upstream commit ebec62bc7ec435b475722a5467d67c720a1ad79f ]

Add missing close() to avoid leaking perf events.

In past perfs this mattered little as the function was just used by 'perf
list'.

As the function is now used to detect hybrid PMUs leaking the perf event
is somewhat more painful.
