IB/hfi1: Remove module parameter for KDETH qpns

Browse Source 
The module parameter for KDETH qpns is being removed in favor
of always using the default value of 0x80 as the qpn prefix.
Defines have been added for various KDETH values including
the prefix of 0x80.
The reserved range now starts at the base value for KDETH
qpns (0x80) and extends up to and including the last qpn for
other reserved QP prefixed types.
Adjust other QP prefixed define names to match KDETH defined
names.
