Sebastian Sanchez 6d6b8848c8 IB/hfi1: Optimize packet type comparison using 9B and bypass code paths
The packet type comparison used to find out if a packet is a bypass
packet in the hot path is an expensive operation as seen in a profile.

Determine packet's pkey and migration bit through the bypass and 9B
code paths instead.
