perf/core: Simplify the perf_event_alloc() error path
[ Upstream commit c70ca298036c58a88686ff388d3d367e9d21acf0 ]
The error cleanup sequence in perf_event_alloc() is a subset of the
existing _free_event() function (it must of course be).
Split this out into __free_event() and simplify the error path.
