When querying the calling task itself (pid == 0 or the caller's own pid), nxsched_get_param() only filled in sched_priority and never touched the SCHED_SPORADIC related members (sched_ss_low_priority, sched_ss_max_repl, sched_ss_repl_period and sched_ss_init_budget). With CONFIG_SCHED_SPORADIC enabled, the caller received uninitialized stack garbage in these fields, and a task running under the sporadic policy could not retrieve its own sporadic parameters. Fix this by factoring the sporadic parameter fill-in into a common helper nxsched_get_sporadic_param() shared by both the self-query and the lookup paths, so both paths now return identical information. The self-query path keeps its original fast-path behavior: no TCB lookup and a lock-free read of sched_priority. Only the read of the sporadic state is wrapped in a critical section, because tcb->sporadic may be freed concurrently, e.g. by sched_setscheduler() from another CPU switching the task away from SCHED_SPORADIC.
