mm/damon/stat: fix memory leak on damon_start() failure in damon_stat_start()
Destroy the DAMON context and reset the global pointer when damon_start()
fails. Otherwise, the context allocated by damon_stat_build_ctx() is
leaked, and the stale damon_stat_context pointer will be overwritten on
the next enable attempt, making the old allocation permanently
unreachable.
