xfs: remove kmem_alloc_io()
Since commit 59bb47985c1d ("mm, sl[aou]b: guarantee natural alignment
for kmalloc(power-of-two)"), the core slab code now guarantees slab
alignment in all situations sufficient for IO purposes (i.e. minimum
of 512 byte alignment of >= 512 byte sized heap allocations) we no
longer need the workaround in the XFS code to provide this
guarantee.
Replace the use of kmem_alloc_io() with kmem_alloc() or
kmem_alloc_large() appropriately, and remove the kmem_alloc_io()
interface altogether.
