afs: Make error on cell lookup failure consistent with OpenAFS
When kafs tries to look up a cell in the DNS or the local config, it will translate a lookup failure into EDESTADDRREQ whereas OpenAFS translates it into ENOENT. Applications such as West expect the latter behaviour and fail if they see the former. This can be seen by trying to mount an unknown cell: # mount -t afs %example.com:cell.root /mnt mount: /mnt: mount(2) system call failed: Destination address required.
