IA64: fix fp fault/trap handler.
This patch is a part of fixes to bug reported as
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1392
When fpswa handler fails to get a bundle in guest,

When the fpswa library

It tries to get a bundle in guest.
Make it more robust using vmx_get_domain_bundle() instead of
__get_domain_bundle().
