Subject: [PATCH net 2/4] tools: ynl-gen: use macro for binary min-len check

This patch changes the generated min-len check for binary
attributes to use the NLA_POLICY_MIN_LEN() macro, and thereby
ensures that .validation_type is not left at NLA_VALIDATE_NONE.

This doesn't change any currently generated code, as it isn't
used in any specs currently used for generating code.

Fixes: be5bea1cc0bf ("net: add basic C code generators for Netlink")
