Log Message:
Set frame = NULL in XENPV whether DIAGNOSTIC or not.

For Xen PV, the interrupt logic stores the relevant information in
the CPU's struct cpu_info, and CLKF_USERMODE and CLKF_PC don't use
the frame argument at all.  (For Xen PVH, we behave like normal x86
and use the frame as passed.)

DIAGNOSTIC shouldn't change the data flows that affect non-DIAGNOSTIC
logic, so let's just unconditionally set frame = NULL for XENPV.  If
this makes a difference, that's a bug -- and it's a bug that should
not be concealed by enabling DIAGNOSTIC.
