score: Simplify _Scheduler_Get_by_id()

Avoid dead code in non-SMP configurations. Return scheduler identifier
independent of the current processor count of the scheduler via
rtems_scheduler_ident(), since this value may change during run-time.
Check the processor count in _Scheduler_Set() under scheduler lock
protection.

Update #2797.
