    zfs: Update use of UMA-related symbols in arc_available_memory
    
    da76d34 repurposed the use of UMA_MD_SMALL_ALLOC in a way that breaks
    arc_available_memory on -CURRENT. This change ensures that
    arc_available_memory uses the new symbol while maintaining compatibility
    with older FreeBSD releases. This change was submitted to upstream
    as well.
    
    Approved by:    markj (mentor)
    Fixes:  da76d34
