IB/qib: Modify software pma counters to use percpu variables
The counters, unicast_xmit, unicast_rcv, multicast_xmit, multicast_rcv
are now maintained as percpu variables.
The mad code is modified to add a z_ latch so that the percpu counters
monotonically increase with appropriate adjustments in the reset,
read logic to maintain the z_ latch.
This patch also corrects the fact the unitcast_xmit wasn't handled
at all for UC and RC QPs.
