[ Upstream commit b94729919db2c6737501c36ea6526a36d5d63fa2 ]
The compiler reports that free_sys_event_tables() is dead code.
But according to the semantics, the "LIST_HEAD(sys_event_tables)" should
also be released, just like we do with 'arch_std_events' in main().
Fixes: e9d32c1bf0cd7a98 ("perf vendor events: Add support for arch standard events")
