Use MAX_PARALLEL_WORKER_LIMIT for max_parallel_maintenance_workers

max_parallel_maintenance_workers has been introduced in 9da0cc35284b,
and used a hardcoded limit of 1024 rather than this variable.

max_parallel_workers and max_parallel_workers_per_gather already used
MAX_PARALLEL_WORKER_LIMIT (1024) as their upper-bound since
6599c9ac3340.
