Make the inodes the default management vehicle for struct efivar_entry, so they are now all freed automatically if the file is removed and on unmount in kill_litter_super(). Remove the now superfluous iterator to free the entries after kill_litter_super(). Also fixes a bug where some entry freeing was missing causing efivarfs to leak memory.
