Why? It's 100% backwards compatible.

This enables rt_clock timers to use nanosecond resolution, just by
using the _ns functions; there is really no reason to forbid that.
Migrated timers are all using vm_clock (of course; but I checked that
anyway) so the timers in the savevm files are already in nanosecond
resolution. So this patch
The following conditions can cause cpu_has_work(env) to become true:
- env->queued_work_first: run_on_cpu is already kicking the VCPU
- env->stop = 1: pause_all_vcpus is already kicking the VCPU
- env->stopped = 0: resume_all_vcpus is already kicking the VCPU

Fix this by limiting the access to the allowed range.

The code doesn't make much sense right now, but it will as
soon as timers will be able to scale their resolution arbitrarily.
