Re: [PATCH] raid5: use kmalloc_array() for GFP_NOIO flag

Commit b330e6a49dc3 ("md: convert to kvmalloc") uses kvmalloc_array()
to allocate memory with GFP_NOIO flag in resize_chunks() via function
scribble_alloc(),
2269	err = scribble_alloc(percpu, new_disks,
2270			     new_sectors / STRIPE_SECTORS,
2271			     GFP_NOIO);

Indeed kvmalloc() inside kvmalloc_array() does not accept non GFP_KERNEL
compatible flags, it means GFP_NOIO will make kvmalloc_node() call
kmalloc_node() instead, which is not the above listed code wants.

For md raid1 and raid10 code, such allocation just simply calls
kmalloc_array(), which is enough and works fine. This patch removes
the misleading kvmalloc_array() and simply uses kmalloc_array() as
md raid1 and raid10 code do.
