Subject: [PATCH 1/2] main: don't show splash from cancel_pending_delayed_show

It was a weird to show something in a function called "cancel..show"

Instead move the logic to the one caller that actually needed that
functionality (on_ask_for_password)

Subject: [PATCH 2/2] main: cancel show_splash timeout on deactivate

This fixes a race/crash where plymouthd get deactivated
right before the show timer fires and it tries to
show itself after things have been torn down.
