KVM: PPC: Book3S HV: Increase timeout for grabbing secondary threads
Occasional failures have been seen with split-core mode and migration
where the message "KVM: couldn't grab cpu" appears. This increases
the length of time that we wait from 1ms to 10ms, which seems to
work around the issue.
Fixes: BZ 110865
