netlink: fix policy dump for int with validation callback
Recent devlink change added validation of an integer value
via NLA_POLICY_VALIDATE_FN, for sparse enums. Handle this
in policy dump. We can't extract any info out of the callback,
so report only the type.
Fixes: 429ac6211494 ("devlink: define enum for attr types of dynamic attributes")
