eve: revert ethernet addresses when needed

EVE logging has a direction parameter that can cause the logging
of an application layer to be done in a direction that is not linked
to the packet. As a result the source IP addres could be assigned the
MAC address of the destination IP and reverse.

This patch addresses this by propagating the direction to the ethernet
logging function and using it there to define the correct mapping.

Issue #6405
