[PATCH v2 02/17] afs: Fix error code in afs_extract_vl_addrs()

[David Howells <dhowells@redhat.com>]

From: Dan Carpenter <error27@gmail.com>

The error codes on these paths are only set on the first iteration
through the loop.  Set the correct error code on every iteration.

Fixes: 0a5143f2f89c ("afs: Implement VL server rotation")
