Pavel Begunkov 3a6e1616e8 io_uring: fix poll/netmsg alloc caches ... commit fd30d1cdcc upstream. We increase cache->nr_cached when we free into the cache but don't decrease when we take from it, so in some time we'll get an empty cache with cache->nr_cached larger than IO_ALLOC_CACHE_MAX, that fails io_alloc_cache_put() and effectively disables caching.
