sparc: force resched on IPI
This replicates 1a229e67e4cf08a539fc558d017a95ff03705ac5 for sparc64.
This is what happens:
smp_send_reschedule()
-> smp_receive_signal() (smp.c)
~~> IPI
~~> xcall_receive_signal (ultra.S)
~~> soft interrupt (ttable.S)
-> smp_receive_signal_client (smp.c)
-> set_tsk_need_resched()
