CA-219763: If the PV drivers have been detected, raise an update

Since this is an update to a VIF or VBD, the usual logic only causes an update for the relevant device. Thus xapi didn't know to look at the VM again, and hence might not update the pv_drivers_detected field. This commit adds an explicit update to the VM if the pv_drivers_detected field changes from false to true. Signed-off-by: Jon Ludlam <[email protected]>
