device: Add auto-cleanup function to unset the current action

Browse Source 
This is useful in the functions where we have to unset the device's
current action but we may use early-return to handle multiple conditions
such as in open, close and delete functions.
The latest also currently is a bit buggy as it won't reset the state on
some failures.
