pay: still use channels for routehints even if peer says it's disabled.

Browse source 
We have a report that LND said our (unannounced) channel was disabled, so we didn't
use it for routehints.  We're better off ignoring that in this case (if the peer is
actually not connected, the routehint code will check that and ignore anyway).

Fixes: #6555
