Now the partially empty slub will be frozen when taken out of node partial
list, so the __slab_free() will know from "was_frozen" that the partially
empty slab is not on node partial list and is a cpu or cpu partial slab
of some cpu.

But we will change this, make partial slabs leave the node partial list
with unfrozen state, so we need to change __slab_free() to use the new
slab_test_node_partial() we just introduced.
