[PATCH v4 02/21] afs: Fix error code in afs_extract_vl_addrs()

[David Howells]

From: Dan Carpenter <error27 at 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")
