Mike Marciniszyn d61ea0751a IB/hfi1: Fix a wrapping test to insure the correct timeout 
The "2 * UINT_MAX"  statement:
	if ((u64)(ts - cce->timestamp) > 2 * UINT_MAX) {

is equivalent to:
	if ((u64)(ts - cce->timestamp) > UINT_MAX - 1) {

This results in a premature timeout of the cong log entry.

Fix by using unsigned 64 bit integers, removing casts, and using
an algebraic equivalent test to avoid the "2 * UINT_MAX" issue.

Also make use of kernel API to get nanoseconds instead of
open coding.
