dirlist: fix panic when disconnecting with dirlist-tree=false

Commit 2027223a created a panic when attempting to clear the dirlist
when the config option dirlist-tree is set to false.

This patch fixes that panic by creating a dirlist.ClearList() function
to prevent needing to check a callback.

Tested with both dirlist-tree=false and true
