[PATCH] afs: remove redundant overwriting of ret

[Anastasia Belova]

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.
