From: Lai Jiangshan <jiangshan.ljs@xxxxxxxxxxxx>
When in XENPV, it is already in the task stack, and it can't fault for
native_iret() nor native_load_gs_index() since XENPV uses its own pvops
for IRET and load_gs_index(). And it doesn't need to switch the CR3.
So there is no reason to call error_entry() in XENPV.
