Workaround panic: fpudna from userland
i386 Xen PV domU get spurious fpudna traps from userland. Older eager FPU
contact switching code took care of ignoring them. When transitioning
from eager switching to awlays switching, this special handling was
removed, causing "fpudna from userland" panics.
This change restores the previosu behavior where fpudna traps from
userland are ignored on Xen PV domU.
