[PATCH] IB/ipath: Translate legacy diagpkt into newer extended diagpkt

[PATCH] IB/ipath: Translate legacy diagpkt into newer extended diagpkt

[Dennis Dalessandro]

This patch addresses an issue where the legacy diagpacket is sent in from the
user, but the driver operates on only the extended diagpkt. This patch
specifically initializes the extended diagpkt based on the legacy packet.
