app: delete workarounds for driver callback deadlocks

Browse Source 
Driver methods are invoked during event processing, but some of them may
generate events that would in turn deadlock because event processing is
not re-entrant. However, a previous change moved all such calls outside
event processing and so chained events can no longer deadlock.

This change deletes the workarounds.
