Hard restore with X asks before dropping staged pins

X dropped staged pins without a question, including the selected
submodule's own pin, which the loss check didn't count. A staged pin is
a decision, and X sits one Shift away from x, so dropped staged pins now
count as a loss and make X ask (D31, amends D30).
