xen64: deal with extra words Xen pushes onto exception frames
Xen pushes two extra words containing the values of rcx and r11. This
pvop hook copies the words back into their appropriate registers, and
cleans them off the stack. This leaves the stack in native form, so
the normal handler can run unchanged.
