libfstree: add an assertion that root is not NULL
If the path argument is "", we assume that referes to root and set
the *existing* target node to the root node and skip ahead across
the tree search. This leaves "name" uninitialized, which makes
coverity panic, because fs->root could be NULL, going down the wrong
path.
Obviously, this should never, *ever* happen and there is no reasonable
recovery strategy if it suddenly does, so simply add an assertion.
