nl-cache: free nlc_conf_t in fini()
The (xlator_t*)->private structure in negative-lookup-cache is allocated in the init() function of the xlator, but never free'd. Valgrind detected this as: 656 bytes in 1 blocks are definitely lost in loss record X of Y at 0x..+ calloc (/builddir/build/BUILD/valgrind-3.11.0/coregrind/m_replacemalloc/vg_replace_malloc.c:711) by 0x.. __gf_calloc (/usr/src/debug/glusterfs-3.11dev/libglusterfs/src/mem-pool.c:117) by 0x.. init (/usr/src/debug/glusterfs-3.11dev/xlators/performance/nl-cache/src/nl-cache.c:669) by 0x.. __xlator_init (/usr/src/debug/glusterfs-3.11dev/libglusterfs/src/xlator.c:472) by 0x.. xlator_init (/usr/src/debug/glusterfs-3.11dev/libglusterfs/src/xlator.c:498) by 0x.. glusterfs_graph_init (/usr/src/debug/glusterfs-3.11dev/libglusterfs/src/graph.c:321) by 0x.. glusterfs_graph_activate (/usr/src/debug/glusterfs-3.11dev/libglusterfs/src/graph.c:693) by 0x.. glfs_process_volfp (/usr/src/debug/glusterfs-3.11dev/api/src/glfs-mgmt.c:79) by 0x.. glfs_volumes_init (/usr/src/debug/glusterfs-3.11dev/api/src/glfs.c:160) by 0x.. glfs_init_common (/usr/src/debug/glusterfs-3.11dev/api/src/glfs.c:868) by 0x.. glfs_init@@GFAPI_3.4.0 (/usr/src/debug/glusterfs-3.11dev/api/src/glfs.c:913) by 0x.. main (/root/gluster-debug/gfapi-load-volfile/gfapi-load-volfile.c:54) When the xlators is unloaded, it should free the resources it allocated. This can easily be done in the fini() function.
