IB/ipath: Change use of constants for TID type to defined values

Browse source 
Define pkt rcvd 'type' in a way consistent with HW spec and chips.

The hardware considers received packets of type 0 to be expected, and
type 1 to be eager. The driver was calling the ipath_f_put_tid
functions using a variable called 'type' set to 0 for eager and to 1
for expected packets.  Worse, the iba6110 and iba6120 drivers used
those values inconsistently.  This was quite confusing.  Now
everything is consistent with the hardware.
