The env->hflags is computed in ppc_cpu_reset(), using the MSR register
as input. But at the point ppc_disas_set_info() is called the MSR_LE bit
in env->hflags doesn't contain the same information that env->msr.

, like process stalls, could happen
after migration.
So, this patch checks the runstate of guest in the pre_save handler and
do not re-reads the timebase in case of paused state (cold migration).

If the guest is running a workload like HTC, a side-effect of
this is a lot of process stall messages (with call traces) in
the kernel guest.
