Log Message:
Avoid sneaking past signal delivery in sa_upcall_userret():
generate unblocked upcalls in sa_unblock_userret(), before signal
delivery/p_userret handling in userret().

Also defer getting state for preempted upcalls because on some ports
preemption can happen between sa_unblock_userret() and sa_upcall_userret().
