staging: comedi: mite.h: needs <linux/slab.h>

As reported by the kbuild test robot:

Commit: 0bdab509bf9c6d838dc0a3b1d68bbf841fc20b5a
staging: comedi: usee comedi_alloc_devpriv

Removed the include of <linux/slab.h> from many of the comedi drivers.
Unfortunately, this header uses kfree() in an inline function.

Instead of adding <linux/slab.h> to each of the drivers that use this
header, include slab.h here.

staging/lustre/obdclass: use a dummy structure for lu_ref_link

Move the definition of struct lu_ref_link to lu_ref.h.  If USE_LU_REF
is not defined then define it to be the empty struct.  Change the
return type of lu_ref_add() and lu_ref_add_atomic() to void.  Add
lu_ref_add_at() taking same arguments as lu_ref_add() togerther with a
pointer to a struct lu_ref_link and returning void.  Adjust all
structures containing a lu_ref_link pointer to contain a struct
lu_ref_link instead.  Use lu_ref_add_at() and lu_ref_del_at() to
handle embedded lu_ref_links.

[Original patch mainly changes lu_ref.[ch] but in upstream client we don't
have lu_ref code in the hope of moving to kobject refcounting. So the patch
only picks the other pieces of original patch, in order to keep code in
sync and make it easier to port future patches.]
