Log Message:
avoid calling into the pool code while holding sched_lock
since both pool_get() and pool_put() can call wakeup().
instead, allocate the struct sadata_upcall before taking
sched_lock in mi_switch() and free it after releasing sched_lock.

clean up some modularity warts by adding a callback to
struct sadata_upcall for freeing sa_arg.
