Yang Yang 546b68ac89 openvswitch: validate MPLS set/set_masked payload length ...

validate_set() accepted OVS_KEY_ATTR_MPLS as variable-sized payload for
SET/SET_MASKED actions. In action handling, OVS expects fixed-size
MPLS key data (struct ovs_key_mpls).

Use the already normalized key_len (masked case included) and reject
non-matching MPLS action key sizes.

Reject invalid MPLS action payload lengths early.

Fixes: fbdcdd78da ("Change in Openvswitch to support MPLS label depth of 3 in ingress direction")
