Eli Cohen b51e4b0ac6 IB/mlx5: Fix kernel to user leak prevention logic 
commit de8d6e02ef upstream.

The logic was broken as it failed to update the response length for
architectures with PAGE_SIZE larger than 4kB. As a result further
extension of the ucontext response struct would fail.

Fixes: d69e3bcf79 ('IB/mlx5: Mmap the HCA's core clock register to user-space')
