[ovs-dev] [PATCH v2 4/6] socket: Fix uninitialized values in inet_parse_ functions.

[Mike Pattrick]

Clang's static analyzer will complain about uninitialized value
dns_failure because we weren't setting a value for dns_failure in all
code paths.

Now we initialize this in the error conditions of inet_parse_passive and
inet_parse_active.

Fixes: 08e9e5337383 ("ovsdb: raft: Fix inability to read the database with DNS 
host names.")
Fixes: 5f219af8b3c7 ("ovsdb-server: Fix handling of DNS name for listener 
configuration.")
