Subject: [PATCH] fs/ntfs3: Fix memory leak in indx_find_sort()

When popping a level from the index lookup stack, indx_find_sort() frees
the struct indx_node but not the index buffer it owns. Every call that
descends and then pops a level leaks that allocation.

Free n->index before freeing the node itself.
