Leon Romanovsky 9b6d3bbc13 RDMA/mlx5: Prevent overflow in mmap offset calculations
The cmd and index variables declared as u16 and the result is supposed to
be stored in u64. The C arithmetic rules doesn't promote "(index >> 8) <<
16" to be u64 and leaves the end result to be u16.

Fixes: 7be76bef32 ("IB/mlx5: Introduce VAR object and its alloc/destroy methods")
