    uxa: Align surface allocations to even tile rows
    
    Align surface sizes to an even number of tile rows to cater for sampler
    prefetch. If we read beyond the last page we may catch the PTE in a
    state of flux and trigger a GPU hang. Also detected by enabling invalid
    PTE access checking.
