    video/lfb: switch to xv[mz]alloc*()
    
    Use the more "modern" form, thus doing away with effectively open-coding
    xmalloc_array() at the same time. While there is a difference in
    generated code, as xmalloc_bytes() forces SMP_CACHE_BYTES alignment, if
    code really cared about such higher than default alignment, it should
    request so explicitly.
    
    Also clear the pointers when freeing them.
