Zide Chen aee9f3c666 hv: reset per cpu sbuf pointers during vcpu reset ... When shutting down SOS VM, the shared sbuf is released from guest OS, but the per cpu sbuf pointers in hypervisor keep inact. This creates a problem that after SOS is re-launched, hypervisor could write to the shared buffer that no longer exists. This patch implements sbuf_reset() and call it from reset_vcpu() to reset sbuf pointers.
