openvswitch: Fix push/pop ethernet validation
[ Upstream commit 46ebe2834ba5b541f28ee72e556a3fed42c47570 ]
When there are both pop and push ethernet header actions among the
actions to be applied to a packet, an unexpected EINVAL (Invalid
argument) error is obtained. This is due to mac_proto not being reset
correctly when those actions are validated.
