[PATCH] staging: lustre: obd_support: Add obd_cpt_alloc function

[Julia Lawall]

Summarize OBD_CPT_ALLOC_GFP, OBD_CPT_ALLOC, and OBD_CPT_ALLOC_PTR as a
function, obd_cpt_alloc.

Signed-off-by: Julia Lawall <Julia.Lawall at lip6.fr>

Some questions: Is the name OK?  Is the NULL test needed?  If not, should
the call to kzalloc_node with the call to cfs_cpt_spread_node just be
inlined into the call sites?
