IB/ipath: Maintain active time on all chips

There is a count of "active hours" maintained in EEPROM, to aid
troubleshooting. The definition of "active" is based on traffic
exceeding a threshold in any given 5-second polling interval. As
originally written, the check was inadvertently bypassed for chips whose
counters were 64-bits wide, and only applied to chips with 32-bit wide
counters.

This patch moves the test for amount of traffic "out" to a more common
location, rather than depending on a side-effect of the software
emulation of 64-bit counts on chips whose hardware is only 32-bits wide.
