fs/fscache/stats.c: fix memory leak
There is a kernel memory leak observed when the proc file /proc/fs/fscache/stats is read. The reason is that in fscache_stats_open, single_open is called and the respective release function is not called during release. Hence fix with correct release function - single_release().
