hw/xen/xen-hvm-common.c: convert DPRINTF to tracepoints

Browse source 
Tracing DPRINTFs to stderr might not be desired. A developer that relies
on tracepoints should be able to opt-in to each tracepoint and rely on
QEMU's log redirection, instead of stderr by default.

This commit converts DPRINTFs in this file that are used for tracing
into tracepoints.
