x86, UV: Remove BAU check for stay-busy
Remove a faulty assumption that a long running BAU request has
encountered a hardware problem and will never finish.
Numalink congestion can make a request appear to have
encountered such a problem, but it is not safe to cancel the
request. If such a cancel is done but a reply is later received
we can miss a TLB shootdown.
We depend upon the max_bau_concurrent 'throttle' to prevent the
stay-busy case from happening.
