[Xen-devel] eliminate duplicate stack trace during bad page fault

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

Other than native i386 code, the page fault handler in the guest for whatever 
reason ran a stack_trace even though another one is run from die(). Since 
screen space is limited, duplicating (perhaps long) stack traces seems quite 
wasteful. Patch removing this duplication below/attached.
