[PATCH] driver core: class: fix documentation for class_create()

[Greg Kroah-Hartman]

In commit dcfbb67e48a2 ("driver core: class: use lock_class_key already
present in struct subsys_private") we removed the key parameter to the
function class_create() but forgot to remove it from the kerneldoc,
which causes a build warning.  Fix that up by removing the key parameter
from the documentation as it is now gone.
