Conghui Chen 4d88b2bb65 hv: bugfix for sbuf reset
The sbuf is allocated for each pcpu by hypercall from SOS. Before launch
Guest OS, the script will offline cpus, which will trigger vcpu reset and
then reset sbuf pointer. But sbuf only initiate once by SOS, so these
cpus for Guest OS has no sbuf to use. Thus, when run 'acrntrace' on SOS,
there is no trace data for Guest OS.
To fix the issue, only reset the sbuf for SOS.
