Subject: [PATCH] afs: remove redundant overwriting of ret

ret is the result of dns lookup. There are several
ways to handle different errors (described by switch).
So it is necessary to keep the return value of afs_dns_query.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: d5c32c89b208 ("afs: Fix cell DNS lookup")
