Propagate success status of ftp_close() to userland

The docs say that this function returns true on success, and false on
error. This function always returns true in the current implementation
because the success return value from ftp_close() is never propagated to
userland. This affects one test: since the test server exits after an
invalid login, the ftp close correctly fails (because the server has
gone away).
