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