IB/mlx5: Fix kernel to user leak prevention logic
commit de8d6e02efbdb259c67832ccf027d7ace9b91d5d 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: d69e3bcf7976 ('IB/mlx5: Mmap the HCA's core clock register to user-space')
