secret: Introduce listUnlinkSecret

Browse Source 
Add a temporary helper to search for a specific secret by address
on the list and remove it if it's found. The following patch will
introduce a common allocation and listInsert helper. That means
error paths of the routines calling would need a way to remove the
secret off the list.
