[PATCH 6/7] xen/sched: null: migrate to new sched_ops

Declare sched_null_def as a struct sched_ops instead of a struct
scheduler, dropping the .sched_data field, and register it with
REGISTER_SCHED_OPS() so it is found through sched_ops_array[]
instead of schedulers[].

This moves the null scheduler onto the new sched_ops
registration path.
