slab: change return type of kmem_getpages() to struct page
It is more understandable that kmem_getpages() return struct page.
And, with this, we can reduce one translation from virt addr to page and
makes better code than before. Below is a change of this patch.
* Before
text data bss dec hex filename
22123 23434 4 45561 b1f9 mm/slab.o
* After
text data bss dec hex filename
22074 23434 4 45512 b1c8 mm/slab.o
And this help following patch to remove struct slab's colouroff.
