    libxc: fix vNUMA memory allocation
    
    Only 4KB allocation was using new_memflags.  We should use new_memflags
    in for 2MB and 1GB allocation as well because that variable contains
    node information.
    
    Without this patch, when creating a HVM guest with vNUMA, because the
    node information was not present in the flags passed to libxc, actual
    memory allocation didn't comply with what user specified. With this
    patch the behaviour is correct.
