[PATCH] x86/PVH: Dom0 "broken ELF" reporting adjustments

[Jan Beulich]

elf_load_binary() isn't the primary source of brokenness being
indicated. Therefore make the respective log message there conditional
(much like PV has it), and add another instance when elf_xen_parse()
failed (again matching behavior in the PV case).
