xen/blkback: Use kzalloc's, and GFP_KERNEL for data structures.
The patch titled:"xen/blkback: Use 'vzalloc' for page arrays and pre-allocate pages."
allocates the structures and its member variables using the 'vzalloc'.
Daniel Stodden pointed out that vzalloc is good when we use
big number of pages - while these are at the max two pages.
We can do this using kzalloc. Also the GFP_HIGHMEM does not
work properly with Xen, so take that out.
We will have to revisit this when a "get_empty_pages_and_pagevec"
type API shows up to leverage that.
