Rosen PenevandMichael S. Tsirkin 4d130b63bd vdpa/mlx5: Use kvzalloc_flex() for MTT command memory ...

The create mkey command memory embeds the MTT array as a flexible array
member. Use kvzalloc_flex() to allocate it directly instead of open-coding
the struct_size() calculation with kvcalloc().

The MTT allocation still needs to be aligned to MLX5_VDPA_MTT_ALIGN bytes.
Since each MTT entry is __be64, align the entry count directly and avoid
carrying a separate byte length variable.
