fromupstream: remove patchwork.kernel.org

patchwork.kernel.org has disabled xmlrpc [1]:

  raise ProtocolError(
  xmlrpc.client.ProtocolError: <ProtocolError for patchwork.kernel.org/xmlrpc/: 404 Not Found>

so it's not possible at the moment to pickup patches fromlist
(by msgid.)  Remove patchwork.kernel.org from the pw list.

BUG=none
TEST=tested that the following works
     fromupstream.py msgid://${MY_MESSAGE_ID}
