vfs: Update lookup_dcache() comment
commit 6c51e513a3aa ("lookup_dcache(): lift d_alloc() into callers") removed the need_lookup argument from lookup_dcache(), but the comment was forgotten. Also it no longer allocates a new dentry if nothing was found. Signed-off-by: Oleg Drokin <green@linuxhacker.ru> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
