Unix: fix segfault if ~/.putty/sessions doesn't exist.

Looks as if I introduced this in commit 733fcca2c, where the pointer
returned from enum_settings_start() stopped being the same thing as
the underlying 'DIR *' - I needed to retain a check for the outer
containing structure not being NULL but the DIR * being NULL inside
it.
