H A Dentry_64.Sdiff 64cbd0acb58203fb769ed2f4eab526d43e243847 Mon May 02 22:21:06 CDT 2022 Lai Jiangshan <jiangshan.ljs@antgroup.com> x86/entry: Don't call error_entry() for XENPV

XENPV guests enter already on the task stack and they can't fault for
native_iret() nor native_load_gs_index() since they use their own pvop
for IRET and load_gs_index(). A CR3 switch is not needed either.

So there is no reason to call error_entry() in XENPV.
