keys, dns: Fix size check of V1 server-list header
Fix the size check added to dns_resolver_preparse() for the V1 server-list header so that it doesn't give EINVAL if the size supplied is the same as the size of the header struct (which should be valid). This can be tested with: echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p which will give "add_key: Invalid argument" without this fix.
