sched_ext: Annotate ksyncs with __rcu in alloc/free_kick_syncs()

Browse source

scx_kick_syncs is a per-CPU __rcu pointer, so per_cpu_ptr() returns struct
scx_kick_syncs __rcu **. alloc_kick_syncs() and free_kick_syncs() stored it
in a plain struct scx_kick_syncs **ksyncs, which sparse flags as an __rcu
address-space mismatch. Annotate ksyncs to match. Its accesses already go
through rcu_*_pointer().
