usb: typec: ucsi: Clear EVENT_PENDING under PPM lock
 
Suppose we sleep on the PPM lock after clearing the EVENT_PENDING
bit because the thread for another connector is executing a command.
In this case the command completion of the other command will still
report the connector change for our connector.

Clear the EVENT_PENDING bit under the PPM lock to avoid another
useless call to ucsi_handle_connector_change() in this case.
