Remove clear_current_adv_vars()

The pressure state is already reset implicitly at the end of each block,
meaning an extruder switch will never have to reset the internal state
anyway.

We clear the internal backpressure in the following conditions:

- when switching to a non-LA block
- when quickStop is called
- when the scheduler is idling (losing pressure)
