[PATCH 1/3] trace: include timestamp in trace records added by HVMOP_xentrace

[David Vrabel <david.vrabel@citrix.com>]

From: David Vrabel <david.vrabel@citrix.com>

TRC_GUEST trace records added by the HVMOP_xentrace op are not
timestamped.  Timestamping these records is useful if only TRC_GUEST
records are enabled.
