[PATCH] afs: Fix logically dead code in afs_update_cell

[Gustavo A. R. Silva]

Fix logically dead code in switch statement.

Notice that *ret* is updated with -ENOMEM before the switch statement
at 395:

395                 switch (ret) {
396                 case -ENODATA:
397                 case -EDESTADDRREQ:
398                         vllist->status = DNS_LOOKUP_GOT_NOT_FOUND;
399                         break;
400                 case -EAGAIN:
401                 case -ECONNREFUSED:
402                         vllist->status = DNS_LOOKUP_GOT_TEMP_FAILURE;
403                         break;
404                 default:
405                         vllist->status = DNS_LOOKUP_GOT_LOCAL_FAILURE;
406                         break;
407                 }

hence, the code in the switch (except for the default case) makes
no sense and is logically dead.

Fix this by removing the *ret* assignment at 390:

390     ret = -ENOMEM;

which is apparently wrong.
