sched_ext: Use sizeof_field for key_len in dsq_hash_params
Update the `dsq_hash_params` initialization to use `sizeof_field`
for the `key_len` field instead of a hardcoded value.
This improves code readability and ensures the key length dynamically
matches the size of the `id` field in the `scx_dispatch_q` structure.
