dentry leak in simple_fill_super() failure exit
d_genocide() does _not_ evict dentries; it just removes extra ref pinning each of those. Normally it's followed by shrinking the tree (it's done just before generic_shutdown_super() by kill_litter_super()), but in case of simple_fill_super() nothing of that kind will follow. Just do shrink_dcache_parent() manually. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
