I'm confused here, why do we need the error_out code chunk if no TLVs
may be given? The error_out case covers the logic when there is at
least one mandatory TLV.

Also, wouldn't this be equivalent to just removing the if? I'm
confused and not a python dev :) What I do see is that the error_out
case is needed only if the logic previously added a goto error_out,
which only happens a bit above in that code in another "if
self.input.fields is not None:" check done. That means that removing
the "is not None" from the if will actually not change the code at all
(as there is no real goto error_out being added).
