instrument/daq: Check that self.tempdir has been set before calling os.path.isdir()

Browse Source 
self.tempdir is initialized to None, and os.path.isdir() throws an
exception if you don't pass it a str.  This can happen if teardown()
is called before get_data(), which WA sometimes does.  Check that
self.tempdir has been initializing before calling os.path.isdir().
