x86/uv: Fix the UV BAU destination timeout period
Correct the calculation of a destination timeout period, which
is used to distinguish between a destination timeout and the
situation where all the target software ack resources are full
and a request is returned immediately.
The problem is that integer arithmetic was overflowing, yielding
a very large result.
Without this fix destination timeouts are identified as resource
'plugged' events and an ipi method of resource releasing is
unnecessarily employed.
