xfs: use a separate slab cache for deferred xattr work state

Browse source

Create a separate slab cache for struct xfs_attr_item objects, since we
can pack the (104-byte) intent items more tightly than we can with the
general slab cache objects.  On x86, this means 39 intents per memory
page instead of 32.
