kernfs: move revalidate to be near lookup

While the dentry operation kernfs_dop_revalidate() is grouped with
dentry type functions it also has a strong affinity to the inode
operation ->lookup().

In order to take advantage of the VFS negative dentry caching that
can be used to reduce path lookup overhead on non-existent paths it
will need to call kernfs_find_ns(). So, to avoid a forward declaration,
move it to be near kernfs_iop_lookup().

There's no functional change from this patch.
